Help Finding a Website

Hey guys, it's been a while since I made an actual thread here. I hope everyone is doing well.

Anyways, I stumbled across a website a few months ago and I thought I had got the link to it from here but I can't find anything. Here's what I remember:

- It was in beta.
- It was an invite only thing, like Dribbble.
- I'm not 100% sure, but I think it was being developed by Dan Cedarholm, the creator of Dribbbble.
- It focused on HTML 5's Canvas feature.
- I think it had someone to do with drawing on images with Canvas tools and sharing them, or something like that.

If anyone can tell me what this website is or was, I'd appreciate it greatly.

Thanks!
