A cheap knockoff of tixy.land

Define a function that takes four arguments and returns a value between -1 and 1

1. t: seconds elapsed since loading this page
2. i: the circle number [0, 256]
3. x: the column number [0, 16]
4. y: the row number [0, 16]

Examples

1. (t,i,x,y)=>sin(t * (cos(i+y) + sin(10*i+x)))
2. (t,i,x,y) => sin(x + t) + sin(y + t)
3. (t,i,x,y)=>sin(2*t-.4 *hypot(x, y))
