    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.

That's funny. The lines are made with zeroes! Some creative golfing there!
u/Xen

indeed, swap to 't' then try write name ;-)
u/lewdev

Nice! I like it! Switch 0 with t for interesting results!
u/ximavus

swap it to '_ '.repeat(25) and it looks a bit 3D

🤯 New idea for 3Dish dweets!
