In Pieces - Some of the work on this site is so much on another level it will make you just want to open up a Codepen and just start trying to figure out some of this stuff.
Sketch Talk - A forum for all different types of Sketch comments and questions. Are forums cool again?
Firesize - Image resizing as a service? I can’t decide how I feel about this right now. I feel like I might use the shit out of this during a prototyping phases.
Building a Circular Navigation with SVG - Killer SVG demo to build navigation. It is a nice walkthrough even if you know little about SVG. Sketch Recap
I have been taking a Sketch course and going through a number of different tutorials. The first project we did was replicate the Skype logo. That was much simpler than I thought it would be. The next thing was redesigning the Game Center icon for iOS. I am currently on about v6 and they all look terrible.
