Those programs produce beautiful results guys, thanks for sharing them.

I have been interested in playing with graphics on various screens for years, and it's great when people share things like these.

The reason I ask so many questions in this group, is that I want to get a bit more than the obvious out of the HP Prime too :-).

I am lucky enough to need to use a calculator all day in my work, but I spend my free time, trying to understand each ability (inbuilt function of the calc) deeply, so that I can use it to it's fullest.

Great work. Please, keep sharing.
