And now that I've been reminded of the video thread...
keeps cropping up on my recommendations. They're not tutorials and you don't really learn anything from them, but the gimmicky drawing challenges are annoyingly good in a enviously entertaining way.
Wasn't sure where to post this but seeing as it's a video I'll put it here.
Seen it a couple of times on my YouTube recommendations and it looks interesting if a little gimmicky.
Not sure what kind of specs/GPU it needs but I may download the free trial for a looky loo.
