Here is the promo for the Machinima Expo in Montreal 2008. The deadline is still open until Monday 13th October. Machinima is sort of like the Claymation of the virtual world, because with Claymation you can shoot footage using a still digital camera and with Machinima you can simply capture the footage off your computer. It is made for people like myself who suck at animation but still likes to dabble in different mediums.
One of the most prolific Machinima streaming sites is simply called Machinima. There you will find Machinima created from Halo, World of Warcraft, Second Life, Super Smash Brothers and many more. Whilst many filmmakers struggle to enjoy Machinima, I like to think of it along the lines of cheating animation to have some fun.
