In past week I added number of improvements to 3DTin.
It now sports a gallery of sketches that show what can be achieved with 3DTin. It shows on the right of the canvas and is currently populated by selective sketches. You can just click on them to load in the editor. You can save your own copies of them too. The gallery needs some more tidying up to behave properly on mouse hover, I will get to that later this week.
The toolbars are re-done now. They now look more slim and sexy. (Icons courtesy Pixel-mixer)
Do checkout the new look and let me know what you think.
