Plots of the Exponential Function over the Complex Plane
May 21, 2015, 12:00 amI was inspired by this tumblr post, and this wikimedia page to make some pretty pictures of the exponential function over the complex plane. Go there to read in more detail how the images were created, including how the colors were created.
Code is found here.

It reminded me strongly of the waning moon and linear mod art projects that I’ve been playing with.
For instance, here’s a screenshot from the waning moon (specifically y = 56x)
A quick intro: the pictur...
Linear Modulus Art
April 28, 2015, 12:00 amI saw this fantastic webpage a couple of months back.
Tons of fun. I took that idea and made a gif for my weird art Tumblr, Recursive Processing.
Here’s the processing.org code and the live (and smoother) version, and here’s the more fun version that is interactive based on the mou...
