Here are a few pens from the growing collection of my UI experiments & concepts I hacked out on CodePen.
Here's a silly UI I made poking fun at a hamburger icon and Apple's two-line menu icon. On click, the sandwich smashes together, the cheese melts and the bread gets grill marks.
And here's all the animation (code) I wrote for the original SVG I designed for the front page of my site. I tried various SVG animiation libs but kept coming back to Velocity.js because of its speed, power and ease of use.
