I encourage people to check out and contribute to the gallery, I built this because I wanted to see the amazing things people come up with!

Fan like+circling around with a long period http://maxbittker.github.io/Mojulo/#c2luKCh5KmNvcyh0aW1lLzIx...

neat, can't quite grok the mechanics behind it though

Fan is (y-50)/(x-50)+time/5, sin is to add texture. Multiplying x by cos and y by sine of the same frequency would simply rotate the fan centre around top right corner, slightly off periods (19 and 21) degenerate that circle into a more interesting Lissajous curve.

thanks for breaking it down! I'm adding it to the snazzy new gallery, and implementing Lissajous curves is going to be my new region of exploration

here's one:

  10*((((100-x)^2+y^2)^0.5 + time) % 10) + 10*((((x)^2+y^2)^0.5 + time) % 10)

fantastic effect! One of my favorites today, thank you. Quick question - do you think that I should refine the gallery formatting to include attribution? It's a bit of a "discovery vs invention" type quandary

Just wanted to mention, that gallery link is barely noticeable because of the blue color. I didn't notice it on multiple visits till you mentioned there was a gallery.

Changing the link color should fix it.

haha it's always been purple for me because it's a clicked link! no wonder nobody can find it. thank you
