This contest comes courtesy of the Nerdist, Hot Topic and Her Universe (seriously, does anything make for unlikely bed fellows like an SDCC contest?). It's an Instagram contest and it offers a chance to show off your brainy and technical chops by making a video for Pi Day. The winner gets 4-day passes, flight, hotel and tix to the Nerdist PodcastLive.
The contest runs until 31 March, so move fast. Get more details here.
