I was going through an old hard-drive today, and dug up a bunch of old math art (2001-2006) made in an old windows app called Math GV. This app differs from Mac OSX Grapher and Pov-Ray in many ways – it’s much more primitive in some ways, though since you can set the number of lines, as well as the beginning and end value of theta, a lot of cool effects can be achieved with Math GV which I haven’t been able to replicate on other graphing apps.
