    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Underwater lava cave #perspective

u/tomxor

I keep switching perception between cave and mountain top, it gets stuck on mountain top... i can't control it 😳
u/sigveseb

I don't see mountain top 🤔 how?!
u/tomxor

funny, i can't see anything else now... it;s like looking down from above a mountain peak. Maybe imagine you are looking down from a circling helicopter.
u/rodrigo.siqueira

This #illusion is called "bistable perception". When I posted it was looking like a cave, now it seems to keep changing between mountain top and cave. I prefer a cave.
u/sigveseb

yes, I see it now!
u/rodrigo.siqueira

#tunnel
u/joeytwiddle

To see the mountaintop, maybe look at the blue and imagine it is the floor or the sea, far away.

fixing up the hsl to have commas and closing paren may fix some browsers

Safari is wrong, they should this dweet as a unit test :)
