In this demo the inner corners have been rounded (idea to use Bézier curve and initial code contribution by Isaac Vega Rodríguez) to resemble what modern physical cubes meant for speedcubing actually look like. The amount can be adjusted, enter a number between 0 and 0.50 in the box and press Enter. The corners that are rounded are configurable as can be seen on the second cube. The third cube has all corners rounded. The corners can be straight cut instead of rounded by clicking the checkbox. To see the code for this mod, do ctrl-u for page source and view the javascript code (down the page). Also click on the link for A3_florian.js (near top of page) which is a modified version of AnimCube3.js and search for function drawFlorian.
