Every time I enter something using the variable â€śtimeâ€ť it tells me â€śerror: no such variable: tâ€ť so it doesnâ€™t parse the input very well.

((sin(A * 20 + time/7) + 2) * 30 + (cos(r * (20 + sin(A * 2 + time/83) * 5) + time/11) + 4) * 30) + (sin(x * time / y / 1000) + 2) * 5 - 20

Very peaceful.

r%50Atime*10000

Simple, but hints at fractals. Wait for the red. If you have lots of patience, you can bump the multiplier at the end down.

x * y * timetime
A * time
time

Also hints at fractals.

Nice work getting a smooth gradient! Are the constants derived mathematically or from trial and error?

Iâ€™ve been able to shift the result into different colour channels with the bitwise operators, hereâ€™s 3 of your waves going at different frequencies:

(((((sin(A * 20 + time/14) + 2) * 30 + (cos(r * (20 + sin(A * 2 + time/41) * 5) + time/22) + 4) * 30) + (sin(x * time / y / 1000) + 2) * 5 - 20)*0x0000ff)&0x00ff00)
+
(((((sin(A * 20 + time/7) + 2) * 30 + (cos(r * (20 + sin(A * 2 + time/83) * 5) + time/11) + 4) * 30) + (sin(x * time / y / 1000) + 2) * 5 - 20)*1)&0x0000ff)
+
(((((sin(A * 20 + time/3.5) + 2) * 30 + (cos(r * (20 + sin(A * 2 + time/166) * 5) + time/6) + 4) * 30) + (sin(x * time / y / 1000) + 2) * 5 - 20)*0x00ff00)&0xff0000)

Hereâ€™s a few:

y^(-time)*x^time

or

(256 * ((x - 50)^4 - 6 * (x - 50)^2 * (y - 50)^2 + (y - 50)^4) * (-56860.3008158835 * ((x - 50)^2 + (y - 50)^2)^3 + 989.873854845905 * ((x - 50)^2 + (y - 50)^2)^2)) * sin(time/(3.14 * 10))

(((((sin(x * sin(time/16)/3.14159265)* 128)+128))0x00ff00)&0xff0000)
+
(((((sin(y * sin(time/8)/3.14159265)
128)+128))0x0000ff)&0x00ff00)
+
(((((sin(x * sin(time/8)/3.14159265)
128)+128))*1)&0x0000ff)

If you want to go further with this idea (a data stack! more operators, sound!) - AND you can handle a stack based language based on Forth, I recommend trying IBNIZ. It is quite a bit more complicated if you have hasvenâ€™t userd Forth before (or perhaps postscript). Once you get used to the style, it is a LOT of fun.

If you just want to see what IBNIZ does, the original demo video is rather impressive. (WARNING: VERY LOUD UNFILTERED SQUARE WAVES).

Also, while it unfortunately lacks sound support, a javascript port exists.

If we run the result through a sin() operation for each colour channel, and offset each one by 2/3PI, it keeps the output at roughly the same brightness while changing the hue (i.e. rainbow colours): http://maxbittker.github.io/Mojulo/#KCgoKChzaW4oeCp5KnRpbWUvMTAwMCkgKjEyOCkrMTI4KSkqMHgwMGZmMDApJjB4ZmYwMDAwKSAgKyAgKCgoKChzaW4oeCp5KnRpbWUvMTAwMCsyLjA5NDM5NTEwMjM5KSoxMjgpKzEyOCkpKjB4MDAwMGZmKSYweDAwZmYwMCkgICsgICgoKCgoc2luKHgqeSp0aW1lLzEwMDArNC4xODg3OTAyMDQ3OSkqMTI4KSsxMjgpKSoxKSYweDAwMDBmZik=
