This simulation takes an equation from the user, with variables x, y, and time. It then evaluates the equation for each pixel, and converts the resulting number to a color based on hexidecaml. That means that low numbers (below 50 ish) will look black.

Note: when using Math.cos() and Math.sin(), ensure that there is a coefficient, otherwise the equation will evaulate to numbers between -1 and 1, and will just appear to be solid black. Also, make sure when using Math.sin() and other functions, Math with a capital M is used.

Some examples:

• Math.cos(x*(y|time))*time*time
• x*y*time
• (Math.cos(time+(y/(10*Math.sin(time/20)))+Math.sin(time+(x/(10*Math.sin(time/20))))*(2))*1000)
• ((time-x+y)|(time-y+x)|(time+x+y)|(time-x-y))^6

Valid input variables:

• x, y (where the origin is the top left corner)
• time (measured in frames drawn, starting at 1)
• Standard mathematical signs (+, -, * /)
• Bitwise operations (|, &, ^, <<, >>)
• Javascript math functions (Math.random(), Math.sin(), Math.cos(), Math.pow(), etc.)
• Plain constant numbers (1, 38274, 243.2342)
