Touch the equipment

Not screenshots of work — working things. Everything on this channel runs in your browser, right now, and came off the same bench as the client work.

Hold the canvas down — the color tunes in

Canvas 2D, no WebGL, no libraries. An offscreen pass rasterizes the type; the visible pass redraws it as a dot screen whose radius comes from source darkness. Somewhere on this site, a certain ten-key sequence opens the same panel where you least expect it.

EXP 02

Promotion stack

why order of operations is money

Two discounts on one order — a percentage off and a fixed amount off. Which applies first? Most store owners don't know their platform's answer, and the difference is real margin. Drag the numbers; watch the two orderings diverge.

Percent first, then fixed$130.00Fixed first, then percent$136.00

The house keeps $6.00 more when the fixed promo applies first.

Drupal Commerce and WooCommerce answer this differently out of the box. If you run both discounts and never checked, that's the audit.

EXP 03Liquid lightthe lamp every Dead show projected

The lava lamp, browser edition

A liquid light show in one SVG filter: blur plus an alpha-contrast threshold makes separate blobs read as one goo — the same trick behind every gooey UI since the technique was discovered. Click the lamp to pour in more wax. This is the one channel where color gets to just be.
