If you haven’t seen any HTML5 games, it can be quite inspiring to look at Chrome Experiments, which appeared not long after Chrome Browser became HTML5 friendly. The site lets any developer upload their HTML5 experiment, game, etc. It currently has 413 experiments of which 78 are games, 14 are multi-player and 141 are WebGL.
One of my favorite tools on the site is Background Generator, which is wonderful for creating Photoshop-style backgrounds with textures, gradients, and multiple colors. It’s a designer’s toy that outputs both the graphics and CSS so you can use them on your website.
If you are considering WebGL development, it’s probably a good time to start thinking about it. The 1.0 specification is out and can be found on the official WebGL Wiki. There’s a cookbook and even a WebGL playground where you can experiment with your own code.
I believe there’s enough WebGL support in browsers and developers should think about learning it and using it for web games. WebGL has other uses as well, which Google’s bookcase demonstrates in both Firefox and Chrome.
