Yes, it could be done with Lua edje scripts, as in that case the Lua script is entirely responsible for the placement of widgets. It could do suitable maths calculations just fine. The example edje Lua script does something similar to fill up a rectangle with bubbles. Look at the bubbles/lua group in trunk/edje/src/examples/lua_script.edc. Speed is not an issue, that bubbles code is from an embedded project I'm working on that runs on a x486. Maybe showing us a video of it in use might help, but I agree with others that it looks like a hard to use user interface. -- A big old stinking pile of genius that no one wants coz there are too many silver coated monkeys in the world.
