Hi Chris - thanks for the book and the participation in the forum!
I started your book with my kid and we ran into a problem with the first example. My son typed out the four lines, but nothing changed. I cut and pasted the lines (after triple checking for typos) on two other modern browsers and still no dice. Note that the [gamingjs ice landing page] (http://gamingjs.com/ice/) does correctly render a spinning polyhedron.
The browser we tested on:
- Chrome 34.0.1847.116 beta
- Safari 7.0.3 (9537.75.14)
- Firefox 28
I briefly opened the console to compare with the working example and noticed that there were two additional errors:
Uncaught SyntaxError: Unexpected token ILLEGAL ( preview_frame.html:21) Uncaught TypeError: undefined is not a function (preview_frame.html:22)
