CSAIL Annual Meeting 2011 Puzzle

In what has become a regular event, Erik Demaine and Martin Demaine give out puzzles each year at our lab's Annual Meeting. Here is the 2011 edition.

This puzzle is inspired by the “123456 Folding Puzzle” and the variation “Cardboard Folding Puzzle” by Stef Breukel.

Rules

Fold this puzzle, along the grid lines, down to a 1 × 3 rectangle that spells M-I-T on both sides, in the same color on both sides. There are three puzzles:
  1. red on both sides,
  2. green on both sides, and
  3. blue on both sides.

Bonus puzzle: Fold along the grid lines down to a 1 × 3 rectangle that shows none of the individual M/I/T letters, and instead shows the instructions, goals, and MIT/CSAIL logos (on both sides).

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.
