2D Affine Transformations

"An affine transformation is any transformation that preserves collinearity (i.e., all points lying on a line initially still lie on a line after transformation)..."

Building a Sign

Please tell us about your blog posts or other articles on this subject. Otherwise, Example 9h, here: http://martinrinehart.com/frontend-engineering/knowits/v2/online/09/v2-chapter-09h.html.

Building a Cube

Per the text, we do not recommend any of the standard approaches to making a CSS3 cube. Complete the carousel (Chapter 10) to see why. Compare our method to these.
