For Ironcoder V I put together a nice little Twitter screen saver. Grab it if you like here.

When I began developing Tangle I was playing with different ways of moving circles around. I ended up using the standard drag ideas and selection box mousing techniques. I really wanted a quick, intuitive way to move or rotate a group of vertices. The selection box makes movement possible but the best solution for rotation that I could think of was what graphic apps usually do with dragging on a corner of a selection. That wasn’t ideal, but may be implemented in a future version of Tangle with a fading in/out rotated rectangle around currently selected circles when you mouse over part of your selection.

What I did think would be ideal was multiple points of input. Those circle vertices are just begging to be grabbed by a players fingertips. Many times I’ve wanted to reach up and touch Tangle’s circles on my iMac’s display. The circles are really asking for it.

This leads me to think that Tangle would be great on an iPhone. It’d be perfect to drag the vertices around with your fingers, independent of each other. It’d be easy to pick up and play when you have five minutes and wanted some fun. I’d be very interested in writing this if I could.
