The circle, portal, enchantment, banner and skin tools use no third-party code libraries. Their 3D view and shape maths were written for this site. The distance step in the circle tool follows the published Felzenszwalb and Huttenlocher algorithm, written fresh.

No art, textures, models or sounds here are taken from a game. Banner art and starting skin figures are drawn by BlockJig, and the skin layout is used only as a file format. The enchantment calculator lists plain facts read from game data files, such as names, levels and costs. Its page names the source.
