    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.

Plz put me down alien.

u/5Mixer

This was just a quick one, didn't spend too much time golfing. Interesting but minor discovery, use em as the unit in font size and you might not have to go into double digits.

Thanks for the tip :)

Wanted to see if I could use the box ascii characters for something. Drawing text takes up a lot of characters, but it turned out okay :D As a bonus, removing the '+1' on the final line makes the pattern squares!

u/5Mixer

Edit: Nope. Some golfing apparently means that isn't true anymore lol.

Cityscape! At 170 chars I had it moving quickly, and with much, much better randomisation. To see the paralax work, multiply q=t*o by 10. I would have loved to have had a little car emoji too, but oh well, I'm still new. I've spent way too long trying to shorten this lol.

u/SpecialAgent

You can remove the brackets around r=(r*9e2) to gain an extra two characters, since both * and % fall in the same operator precedence group, then q=t*9 works. Good dwit!
u/Renaud___

s=r/(w*99)*70 can be replaced by s=.7*r/w too it seem
u/SpecialAgent

correction, q=t*o*9 works
u/lionleaf

If you change the dweet itself you can post directly and it becomes a remix. Post the moving one!
u/5Mixer

Woah, thanks for the replies guys. I looked for ages and didn't spot those chars :) Remixed it moving faster.

Some interesting tricks - I use a backwards while loop, not sure if this is shorter. To go from screen width to 256 for colours, I divide by 7. Alot of variable reuse. First one, enjoy heh :)
