CSAIL Semi-Annual Meeting Fall 2009 Puzzle

In what has become a regular event, Erik Demaine and Martin Demaine give out puzzles each year at our lab's Semi-Annual Meeting. Here is the Fall 2009 edition.

This puzzle is based on “Faltpuzzles” (folding puzzles) by Klaus Schröer that appeared in Spektrum der Wissenschaft.

Rules

There are two puzzles, one for each icon/logo (CSAIL logo, and MIT Mens et Manus). In each puzzle, your goal is to fold the rectangular puzzle, only along the gray lines, down to a 2 × 2 square with two complete logos, one on each side.

Printing Notes

This puzzle requires printing images on both sides with fairly close alignment. This can require some fiddling with your printer or photocopier.

The puzzle was designed for color printing, but it will work fine on a black-and-white printer.

The PDF file is the best combination of printing quality and small file size. The PostScript file also has ideal printing quality, but the file is larger. In either case, you need a suitable viewer. Alternatively, you can print one of the images. If you can print images scaled to fit, use 150dpi. Otherwise, use 72dpi.
