4d graphing in Desmos!

In this video I give a showcase of two Desmos projects related to 4d shapes: a point plotter and a cross section getter.
At some point I might make a sequel that gives a rundown of how the code generally works and talks about axes of rotation, etc. Most likely I won’t have the time.

4d video recommendations: (Open to comments!)
Great TED-Ed introduction:    • Exploring other dimensions - Alex Rosentha...  
Everything by 4D toys / Miegakure!
CodeParade’s 4d golf series!
Matt Parker on 4d Platonic solids:    • There are SIX Platonic Solids   - I think I remember this being good but I haven’t watched it recently.

Sorry if the video's a little quiet.
