Caine's Arcade from Nirvan Mullick on Vimeo.
I found this video randomly on one of my internet sprees, and couldn't help but carry on watching. The ideas and inventiveness of this young boys project was so good, but what I really love is how much of a success it has become since this video was made. Caine now goes around schools giving speeches on how to run a business and the importance of creativity, with many children choosing to mimic him and create their own cardboard arcade machines.
