I just found a bunch of videos from 2011 
The app’s name back then was “Codify”.
I built a particle engine, planet simulation and a sine wave generator on my iPad 2.
Watch the videos here.
Do you also have videos of your first Codea projects?
@Frederik I also found your videos in this link.

@Frederik I remember watching those and being blown away by what you had built! Thanks for sharing them again
