Picasa teddy bear - a hidden Easter Egg

Pressing Ctrl-Shift-Y in Picasa brings up a floating teddy bear, which has no particular use beyond simply being a hidden easter egg.  If you repeat the key press you get another bear, at a random position, and random size.  The bear can be moved around by picking and dragging it, so you can try placing it in appropriate places in your photos. 

The Easter Egg is present in both Picasa 2 and in the 2.5 beta. However, as a non-mainstream feature, in Picasa 2.5 it currently shows a number of bugs:

• when dragging the bear around with the mouse, the bear does not move the same amount as you drag the mouse (try picking him up by the center of his nose - as you drag, the mouse moves off his nose)
• when appearing where the search box is, the bear, which normally floats in front of everything, is obscured by the white rectangle of the inner search box
• when switching between albums in the thumbnail view, the bear can lose his head, or appear in multiple parts - as the albums scroll into view, parts of the bear are scrolled with them, rather than the albums scrolling behind the bear

I don't know of a way to get rid of the bear once you have brought it up - you simply have to exit Picasa.
