If you're interested in the fourth dimension, I've written an iOS app that explains what a tesseract is using a series of interactive 3D/4D models: http://fourthdimensionapp.com

It's currently featured in the #3 slot on the home page of the App Store in China and got 4000+ paid installs and 5 stars there this week (wow!)

+1 on that app, I've learned from it.

Wow...so Wikipedia tells me that C.H. Hinton was married to the daughter of George Boole...so that's the Same Hinton as our contemporary 'father of deep learning', Geoffrey Hinton. Quite the family of manifold surfers!
