I don't normally post Hack Design lessons here (maybe I should?) but I found Quartz Composer really interesting. There's an incredibly steep learning curve, but Dave makes it really easy to understand.
Great share! I actually wasn't aware of this website at all before you posted this, and I've been really interested in how to get into Quartz so this is great timing! Thanks again mate :)
Good article. I wan't aware of this site either. I've tried QC and found the learning curve steep and since moved on to using Framer.js due to it's speed.
I was looking at QC awhile ago but didn't jump onboard because of the future support for it is sketchy. I'm afraid to invest a lot of time learning it and it ends up doing a Adobe Fireworks. Anyone can shed some light if there is an advantage picking it up?
