Years ago I made some novelty sites with php/apache that used the subdomain to display different messages to the user, I decided to remake one of them using node and wanted to share how this could be done, it was much simpler than I thought it would be.
I decided to create a small project this weekend, using node, and nodejitsu.com. The concept was really simple, to generate a 2d ship that could be used in games, or any programs really. The project turned out pretty well check out http://retroships.com/. The ships are generated via node-canvas, and displayed to the user. The stars are done with standard client side canvas. Im sure Ill be creating a few more micro sites like this, and possibly a full on app for procedural graphic generation at some point.
