so any help would be appreciated.

on the app, you tapped the screen and it made a dot. then an orange ripple would spread from the dot, and when it collided with other ripples it'd make a note with a pitch appropriate to the size of the circle at the time. you could fiddle with the speed of it all as well as the wave forms i think. it was not Bloom, Musyc or Orphion.

also it MAY have also been a website, but maybe not.

i had it on an ipod touch, about 2 years ago

thanks
