So this is a running list of web pages I’ve found that do something cool with interaction, 3D or data: die shots you can zoom into, walkthroughs of how hardware works, simulations, weird little tools. Each one has screenshots, a short note on what it shows, and a link to the original.
Honestly it’s where most of the ideas for this site come from. You can search it, browse by category, and star the ones worth coming back to.
