After effects

Using whatever effects you choose or create, make a video of at least 30 seconds length to go with any song of your choosing. The goal here is to create a video that is primarily effects, not footage based. 

To create effects based on audio tracks, something like  this simple audio keyframing tutorial  is recommended.

Some random examples of neat effects-based music videos:
