☀️ The glass is blank. The wall isn't.

Hold it up to a window and there's nothing on it. No print. No paint. Then the sun comes through, and a face lands on the wall.

That's a caustic lens. Clear acrylic, its surface shaped so precisely that sunlight draws a picture. They're beautiful, and almost nobody sells them. Every single one needs its own optics solve.

A studio that writes a name, or a face, in sunlight.

Type a name, or drop in a photo. Your browser solves the lens. No server, no AI credits. A ray-traced proof shows the light before anything is cut. Then it checks the glass. The portrait in the video: 3.3° slope, 3.6 mm deep, match 0.80. Ready to cut.

From your city and your window, it finds every day the light is sharp and adds them to your calendar.

Photos were the hard part. A full-contrast face came out 7.1 mm deep, over the 6 mm cut line. So every photo now keeps a soft base glow.

Behind it runs a real workshop. Orders move through each stage on the Workshop board. Today's lenses nest onto one acrylic sheet. Approved pieces hang on the public Light Wall.

One photo. One beam of sun. Zero AI credits.

So whose face goes on your wall? The sun does the rest. ✨

This is such a creative concept! Turning natural sunlight into a medium for portrait creation is a genuinely unique idea. I especially like how you've connected the creative side with a practical workflow, from checking light conditions to production and order tracking. The zero-AI-credits aspect makes it even more interesting!

Aerolith: an autopilot for New York's airspace

At rush hour, New York barely moves, but a trauma bay waiting on blood can't wait. Aerolith is an aerial dispatch network that runs commercial drone work and emergency medical deliveries through one autopilot, built and shipped on @Base44.

What the automation does, with no dispatcher involved: • Prices every request instantly from distance, job type and urgency • Checks live weather at the pickup and calls GO or NO-GO against each aircraft's limits • Finds the nearest aircraft with the right range, battery, payload and cold box, plus a medically cleared pilot • Gives emergency deliveries priority: a booked commercial job yields, is re-slotted, and its client is told why • Moves flights to the next clear window when a storm rolls in, or pages a duty officer for emergencies • Sends live tracking to the client or hospital and logs every decision for audit • Grounds aircraft automatically when they hit their service hours

The result: about 90 minutes of phone-and-spreadsheet dispatch work, done in about 3 seconds.

Design: I wanted it to feel like flying, not like a dashboard. The homepage is a scroll-driven 3D flight over a night-time New York, built in three.js, that follows a Lifeline drone on an emergency run. The rest of the site uses a blue-hour palette, wide type like the lettering painted on an aircraft, and a red lane reserved for emergencies. It's fully responsive on mobile.

The walkthrough film was made from the site's own 3D scene, with a voiceover and score cut to the narration.

Try it: aerolith-e0aa51d9.base44.app Open the Ops console and press "Incoming emergency" to watch the autopilot work live.

A concept demo: the fleet, pilots and facilities are simulated, and the weather is real.

New York very good vibes 😍
