Post your E2 shit here.

I'll start:

Hi, I'm no math nut but when I tried making an EKG, I wanted to play around with some other equations I could use to make shapes on an oscilloscope. I've made plenty already but I will release them every few times. It doesn't exactly do much but look pretty. But some of you may make use of them someday. Like making something float over your head in some fancy way.
If you want to see the design, simply create an oscilloscope and wire the x and y values to that of the e2 chip.
Anyways, first few releases:

Hi, I'm no math nut but when I tried making an EKG...
An EKG? What was it going to measure :|

also, cool stuffs.
