Found this interesting toy for the quiet time between Christmas and New Years. It came from the Windows Secrets Newsletter
WACKY WEB WEEK — playing for you the Internet's greatest bits
Print your own 12-sided 2005 calendar
For your end-of-year festivities, one Web site allows you to define your own 2005 calendar and print it out as a 3-dimensional, 12-sided object that will surely amaze your friends.
The shape is known as a pentagon dodecahedron. You do have to cut and fold the thing. But Ole Arntzen's site could hardly make it any easier. You can select PostScript (for PostScript printers) or PDF (for any Windows printer, assuming you have the free Adobe Reader). The PDF format actually builds itself inside your browser window, after which you simply print as many copies as you like. Happy holidays!
