Cocreate Shared whiteboard tool for drawing, teaching, and brainstorming.

Coauthor Tool for group collaboration, discussion, keeping track of notes/results of meetings, etc. Its primary goal is to ease multiauthor collaboration on unsolved problems in theoretical computer science, so e.g. you'll find LaTeX math support; hopefully it will have applications in other fields too.

Virtual Glass Lets glass blowers design and visualize glass cane, and to get a sense of what that cane will look like on a blown piece, all on your computer (without lifting a pipe!). The goal is to allow the exploration of cane designs, especially new cane designs, and settle on a nice-looking design before going through the effort of making it.

Mathematical Demonstrations

Mathematical and Puzzle Fonts Linkage font represents letters as fixed-angle linkages, which model protein folding. Penland glass squishing font is a video font of forming letters from hot glass. Origami maze font/folder (left) computes the crease pattern to fold a desired maze or message. Hinged dissection font renders letters that can be folded out of a single chain of 128 triangles. Conveyer belt font is a puzzle font where you need to solve a conveyer-belt open problem to read the message.

Interlocked Polygons Illustration of how to interlock polygons that fall apart exactly when a specified Boolean formula is satisfied, as described in a CCCG 2010 paper.
