I've recently followed some Bob Ross videos myself and I can really recommend it - just get a cheap painting kit and pull up one of his videos on YouTube. The Corridor Crew took this one step further: they challenged themselves to recreate one of his scenes while following his video in real time. Good stuff, and impressive results!
The VFX Crew competes to see who can take home the title of "Office Bob Ross" by following along with a "Joy of painting" episode in real time! The only difference is that instead of Paint, they have CGi.
