SVG Motion Paths
Building a simple HTML5 game this week I've learned heaps about motion graphics, Canvas and SVG. I've also learnt a few new tricks with Sass and CSS transitions for keeping my code clean.

Dabblet previewers
I was really impressed when I saw Dabblet by @leaverou. It's simple & fast for editing front-end code and sharing it via gists. The thing that impressed me most was the previewers, the animated pie timer & the measuring rulers in particular. These helpful little bubbles that pop up when you mouse over a keyword in CSS which give a visual representation of the values.
