Neat idea, but feels very poorly made.
The light direction governs the whole grid for some reason but stops outside an arbitrary div and often just stops working period, on top of feeling laggy for such a simple effect.
Channels are messed up. The example doesn't seem to work, while in the video it just makes two edges white for some reason?
The color options and textures are kinda ugly. The glass colors clearly just don't work. "Brass" turns into "Olive" on the last one for no reason?
The radio buttons are a bad idea for a digital interface, implemented completely inconsistently(‽), and the middle one just doesn't work at all.
Buttons have virtually no feedback if they're pressed or not.
Reminds me a lot of Google's material design, at least the older versions of it, just much sloppier and less usable and less colorful.
It supports a dark theme but then you can't see 90% of what it actually does because drop shadows on dark backgrounds just plain don't work.
It’s also glitchy and flickery for me on iOS.
And knobs are a useless control on in any mouse/pointer based interface.
