I wonder if anyone recognizes elements of this project?

This is a final project in a Pd class... the thing is, I didn't teach GEM this semester. So, either one of these students is extremely independently driven and has been playing with GEM on his own (for quite a while, it would seem), or they downloaded a project from somewhere.

I don't want to be too suspicious... but, no harm to ask.

Thanks,

There is an easy way to find out: ask them to explain the code!

The big white ball is the moon, and i've already seen it very long time ago (before electric light pollution disaster era).

I think it's a classic exercise but could be done by a student by himself pretty easily searching informations on the internet. I have teach many courses in China and pd myself few years ago.

You might check if the exercise is somewhere on Aluan Wang website which is still one the best ressources for chinese speaker, even if it is traditional chinese: http://www.dazegraffiti.com/
