I've always been interested in the idea that abstractions can help us discover new relationships that weren't
inherently visible in the implementation that we're trying to tackle. With that thinking in mind, I put together a little engine to help me visualize design patterns that I've drawn. You can navigate the interface with your arrow keys or the "ASDQWE" keys. Unfortunately, fullscreen flash doesn't support keyboard interactions. Without further blabbering, the project is called DPIcon and it's available to play with at dpicon.com.
