Mini-Mau5.

Mini-Deadmau5 from Michael Cobra on Vimeo.

This is almost too awesome for words and would seriously only happen in SF. From Boing Boing: Hip dad Michael Cobra's three year old son really wanted to be Deadmau5 for Hallowe'en, after they saw him play at the Treasure Island Music Festival— so dad obliged. The video above documents the costume's creation. Today, Deadmau5 called the family, and dad says he was totally cool. More at Tiny Iron Fists, and here's the Vimeo link with related comment thread.
