Eastern Eggs for Windows

A virtual Easter egg is an intentional hidden message, inside joke, or feature in a work such as a computer program, web page, video game, television program, movie, book, or crossword. The term was coined—according to Warren Robinett—by Atari after they were pointed to the secret message left by Robinett in the game Adventure. It draws a parallel between the custom of the Easter egg hunt observed in many Western nations and the last Russian imperial family's tradition of giving elaborately jeweled egg-shaped creations by Carl Fabergé which contained hidden surprises.

Easier Way to Force Win in Solitaire

Select the 'Timed game' and 'Standard' scoring options, then play for over 30 seconds. Press Alt + Shift + 2 (above 'w', not keypad 2). This will end the game, add a bonus to your score, and play the celebration. After the celebration (which may be gracefully ended with a mouse click), you are asked "Deal Again?". If you select 'No', and press Alt + Shift + 2 at this point, your bonus will again be added to your score, and the celebration begins anew.

1. Open up the Display controls panel. You can find this in two ways:
a. Go to Control Panel, then double-click on the "Display" entry/icon, or
b. Right-click anywhere on your desktop that is _not_ covered by an icon and click on "Properties".
(Both of these will get you to the exact same place; just use one or the other.)
2. Click on the "Screen Savers" tab, then scroll to "3D Text".
3. Click on the Settings button and tweak the settings this way:

Text: either (although the time will show this off better, IMO)
Rotation: Any (Spin or Tumble recommended)
Surface Style: Here's where the similarity is. It's the same as the one for Windows 98SE (http://www.eeggs.com/items/1959.html) that Nikolas wrote about (just scroll down after clicking the above link for his entry). *Please remember to close the textures window by clicking on the "abort" (the small x in the upper right-hand corner) and NOT the "ok" button!*
You can tweak the rest of the settings as you wish. Be sure to hit "OK" after setting things up or this won't work!

4. Hit the "preview" button to see the new rainbow! (On some machines, the preview window in the tab is too small to view this properly.)
