For the past week I am a little bit busy with the ITP interactive art show in Shanghai. So I made a simple steering effect inspired by this Shiffman's tutorial. I combined my previous firework assignments with the newly learnt thing together to create a grand firework show. Here's the outcome. (The dots on the ground are from the real data of static car geo-locations at one night in Beijing)

Recently I tidy my Github repo since I have too many repos belonging to the same class. So code will be available soon.
