Experiment
It's a dull name, and the tagline won't turn you on either. But it was an awesome experiment and sideproject which helped me understand new development techniques I never used before. Designing the thing in the browser was nice, too. Best of all: it's actually useful to me (I had the idea for ages).
Inspired by Florian Schroiff's Faves (http://faves.fsch.ro/), powered by whatever I like/favorite (through Ifttt) and developed on CodeIgniter with little help from Masonry and Paul Irish' Infinite Scroll.
