Question: what is the website that you mentioned that is with open sources physics programs?

Thanks for asking!

So the idea is to create and collect programs and apps which makes teaching science (probably more physics to start with, since thats my background) fun. For example something which can show equations of motion in action, or the evolution of stars. It will be completely free and accessible to everyone. Even better, if you know a bit of programming and have an idea, or want to improve one of the already existing one, you can just go ahead and do it and share it with everyone.
