In praise of the Leopard mosaic photo screensaver

[For everyone who wanted a video of this screensaver, here you go.]
It was important enough to make the 'Sparta' list, but I hadn't checked out the new mosaic mode for photo screensavers in Leopard until today -- and now I'm wondering where this has been all my life. An infinite outward zoom, creating a Photomosaic-like image that you half-squint to recognize, until... whoomp! It resolves into a picture of one of your pets/kids/scenic byways. Absolutely hypnotic, to the point that when you finally look away the screen still appears to grow and swell for a few seconds more. Put it on a big screen or HDTV and it's a conversation stopper.
Some years ago, when I was working at LIFE, the cover image for the 60th anniversary issue of the magazine was a photomosaic of Marilyn Monroe, produced by Robert Silvers of MIT. LIFE paid Silvers a steep fee to produce the image, and now we have similar capabilities in a screensaver. We truly are living in the future.
Update: Comments hint that you may not be able to run this screensaver unless you have iPhoto '08 installed; if you discover otherwise let us know.
Thanks Rich

Macbook + 24" monitor + lots of RAW = so slow and coppy it's useless.

Constantly crashes for me so I don't use it.

MacPro, 23" Cinema, works like a dream. Sorry to hear you folks don't know how to configure your system. Might check your processes, I had a rogue item that was once slowing mine down. Na na na na naaa na.

This screensaver is very sweet. I have about 10,000 3 meg. photos in my library and the random production of the mosaic is amazing. I am using a G5 iMac with 20" screen.

crashes for me too on a brand new MBP 2.2. i can't even change it back to the first choice: the pics coming down at random. i'm kind of glad i'm not the only one it happens to.

follow up: i think it crashed because i hadn't used iphoto yet, so it had to ask where the library was. once i told it where the library was, and relaunched the screensaver, all is well.
hope this helps some one.

Mine only seems to pull from iPhoto instead of the Pictures folder I pointed it to. I only have a handful of pictures in iPhoto so it's not as good as I'd expect. I wonder why it's ignoring all my other photos?

I love this feature and was wondering if there was anyway to capture this as a quicktime movie. I'd love to be able to use this in an iMovie project for my in-laws 40th Anniversary video. Any help would be greatly appreciated. Thanks.

This is very cool as is the Collage screensaver.
I never would have predicted that Screensavers are part of the reason I like Leopard. Go Figure.

Yes, this is future!
But...also a bit of past. There is the ScreenSaver "ImagePuzzle" which is
very fine
Keep on going foreward!

Works great on my 1 year old MacBook. I suspect that the fact that I have nearly 3500 pics in my iPhoto library may make the whole process a little easier. This is definitely a WOW feature to show off to the uninitiated. The fact that this was an "also ran" new feature makes it all the more impressive. No it won't change the world but it sure is cool.

Just a hint-- If you have any photos you don't want people to see on your screensaver, you should make them "hidden photos" in iPhoto and click off hidden photos before using this screensaver.
No matter which library you choose for the final picture, it draws from ALL your photos that aren't hidden for the collage... So that picture of yourself naked at the office party WILL end up in the collage somewhere.

Works brilliantly on my 12-inch iBook G4 1.33GHz. Looks gorgeous, I literally have to turn my monitor off to get any work done on my PC when it comes on, or I'm just left staring dumbfounded at the pretty mosaic.

i dont see the iphoto library in the selection pane and the mosaic option complains that it can only run from an iphoto library. do i need the latest version of iphoto?

I love it, but it crashes on my 24" iMac C2D 2.8 :-(
I have ~10k photos in my iPhoto library, and most are between 6 and 10 megapixels, but I don't think this is related to the volume or size of photos. It almost feels like it's being triggered by reading invalid files... could it be because I have some rather large "stitched" photos in my library?
