I, like many other have on more than one occasion been sucked into the bottomless vortex that is the internet. So I thought I might as well spend that time where I'm not working watching something that actually might help me.
So, I'll get the ball rolling wtih some of my favorite ones ones:
FZD School of Design - Concept art and design for games and film.
Wolfire Games - Indie game dev vlog, weekly(ish) for the game Overgrowth.
