This time, I tried drawing two fractals on top of each other: "double sin" and "double cos"
To try and explain...
The x position is sin/cos of some imaginary number.
The y position is sin/cos of some imaginary number with the imaginary and real pars flipped.

The result is...nearly impossible to see. Hopefully you're really good at squinting.
