Interesting commentary from Rob Briscoe on some of the decisions that went into the art decisions on Mirror's Edge.
I don't care what you do, if you do it with code this is useful.
Data-driven documents. Such a clever way to do DOM bindings and transformations. So many ideas sparked from this already.
Renaud's slides from his GDC/IGS Fez technical analysis. Full of interesting technical and design points.
Commentary / analysis
Great analysis from Steffen on the breakdown of GL ES 2.0 support on iOS devices.
Informative and practical design interview with Jonathan Blow over on the PA Report.
Resources & tools
Massive community of pixel art & artists.
Ridiculously high-quality fonts on a name-your-price basis.
Kick Starter-funded multi-part image animation for 2d characters. Free beta also available.
Typeface design is cool. Deal with it.
Sources & inspiration
Wonderful game dev for your ears.
Art profile sites, running on Cargo's backend -- full of interesting art and inspiration. The image browse page is a good place to start.
