The company I run

AERI Intelligence

A weather intelligence platform, built for the moment you have to decide what to do.

Most weather apps hand you data. AERI reads it for you: live radar, professional storm analysis, a forecast that explains itself, pressure monitoring, live road cameras and safety tools, in one app, with calm language when it matters most.

Visit aeriweather.com Read the case study

AERI Live Radar Intelligence: a U.S. NEXRAD radar loop over the Southeast with Radar and Storms tabs, AERI Outlook and SPC Outlook layers, and a radar loop timeline. — **Live radar**NEXRAD loop, storm tracking, AERI and SPC outlooks

AERI Today's Forecast at a Glance: 67 degrees and clear, wind, humidity, UV and rain, with a plain-language note and a What is coming section. — **A forecast that explains itself**Tap anything and AERI tells you what it means

AERI Advanced Storm Analysis: Time Weave controls, a Skew-T Log-P diagram with temperature and dew point, CAPE, CIN, LI and LCL values, and a Storm Mode Classifier. — **Advanced storm analysis**Skew-T, hodograph, matrix, trends and a storm mode classifier

AERI Pressure Monitoring With Anchor: a pressure history graph, what the phone can still do, and Strobe, SOS and All clear buttons. — **Anchor**Pressure monitoring, signal quality and phone safety tools

AERI Live Road Cameras Near You: a live highway camera in rain, nearby cameras and moving video cameras from state transportation feeds. — **Live road cameras**See real conditions on nearby roads before you drive

Live radar intelligenceA U.S. NEXRAD radar loop you can scrub, a Storms view, and AERI and SPC outlooks layered right on the map.
Professional storm analysisSkew-T Log-P with CAPE, CIN, lifted index and LCL, a hodograph, a parameter matrix, trends, and a Time Weave to step ahead hour by hour.
A forecast that explains itselfToday at a glance, what is coming and when, in plain sentences. Tap any number and AERI explains it.
AnchorPressure monitoring that keeps working when things get bad: trend and signal quality, a strobe, SOS contacts and an All clear check-in.
Live road camerasLive video and still cameras from state transportation feeds, so you can compare real conditions before you drive.
Three depthsStandard, Meteorologist and Severe: the same app, with the level of detail shaped to the person and the moment.

Built for real decisions.

Step Terra home screen: your island, 86% happy, a season banner, rain showers in the forecast and today's walk of 6,485 steps toward 10,000.

Step Terra island screen: an isometric island in the rain with the hint 'Tap to select, hold an item to move it', an Add item button and your harvest basket.

Step Terra shared sea: friends' islands in an ocean, with Amara's island joined to yours by a bridge.

03KEYAUDIT · KEY CUSTODY

Turning a paper sign-out sheet into a custody system.

Every key has a live state, and a return only closes when a manager confirms a one-time code. Exceptions go through an explicit override and everything exports as an audit record.

Move over it: you are the tornado

How this site works

Hand control is an extra way in, never the only one.

I study human-computer interaction, so the controls on this page are designed to be explained. Here is what they do with your camera, who can use them, and why they behave the way they do.

Privacy

Off until you turn it on. The camera only starts after you press the button and your browser asks permission. Your browser’s camera indicator shows while it’s on.
Analyzed on your device. Hand and face tracking run in your browser. Video frames are never uploaded or saved; only landmark coordinates exist, in memory, and they’re discarded.
One honest caveat: the tracking library loads from jsDelivr and its model files from Google Cloud Storage, so those servers see an ordinary file request, never your video.
The visitor globe records an approximate place (rounded to about 25 km) and country when the page loads, and nothing else. No IP address is stored; a daily-changing one-way hash only stops a refresh from counting twice. No cookies. Do Not Track and Global Privacy Control are honored, and you can opt out below. (Cloudflare, which hosts this site, necessarily sees your IP like any host does.)
Easy to stop. “Turn off camera,” closing the tab, or revoking permission all end it. The optional Lines setting is saved on your device.

Accessibility

Optional, always. Everything works with a mouse, touch or keyboard: buttons, links, and the storm’s size slider (the arrow keys move and resize it too).
Point-and-hold pressing. Hold the cursor on a button for two seconds. The ring fills to show progress, then flashes when the press happens.
Reduced motion respected. If your device asks for less motion, the storm stops moving and the tornado cursor stays off until you ask for it.
Letters always come back. The tornado cursor only borrows them. Screen readers get the real text, never the scattered letters, and the moving letters can’t swallow a click.

Design decisions

Show what the system sees. The skeleton on your hand and the live status line make recognition visible, so you’re never guessing whether it works.
Forgive mistakes. Holding a point presses a button; closing the whole hand toward the thumb and moving scrolls. Opening the hand stops scrolling immediately. The cursor is smoothed so hand tremor doesn’t jitter.
Play, with an undo. The tornado cursor tears words apart and then puts every letter back. Delight shouldn’t cost you the ability to read the page.

Tornado cursorIn the hero, your pointer becomes a vortex that lifts letters off the page, then drops them back. Buttons and links always get the normal cursor. Don’t count my visitKeeps you off the visitor globe. Saved on this device only.

Limits: it follows one hand at a time, works best in good light with the front camera, and needs a secure (https) page. On a phone, prop it up about 2–3 ft away so both your face and hand fit in view. If it can’t see your hand, the status line under the preview says what to try.

Music · Another side of me

I love making music, too.

Music is where I experiment by ear. I built a small hand-controlled studio where you can add harmonies to a voice or play piano keys in the air. There’s also a preview from my Confidence mix.

About Me

A little more about Mustafa.

Hello, my name is Mustafa M. Yildiz. I am 22 years old, born in February, and I am currently studying for my Bachelor’s in Computer Science at Rowan University. In my free time, I love music and writing. For a long time, I honestly disliked computer science, but more recently I deeply fell in love with it after discovering how powerful it can be when it is used to build meaningful systems. I am the founder, owner and solo developer of AERI Intelligence (aeriweather.com), a weather intelligence company focused on making tornado and high-risk weather information easier to understand through clearer design, calmer communication, and more human language in stressful situations.
