3 | Browsing the net today I came accross [Sketch.js](http://soulwire.github.io/sketch.js/) and a [Particle demo](http://soulwire.github.io/sketch.js/examples/particles.html). I quite liked it so spent an hour or so to implement (port js really..) something similar in Swift.

5 | It brought back memories of writing games in action script, which was great.
