While browsing Flickr from the luxurious TUAW offices this afternoon (read: That Starbucks on the corner), we came across the Apple Prototypes Flickr group. There's some very cool stuff pictured, including a penlite prototype with duodock and a transparent SE/20.
As the group's administrator notes, prototype Apple hardware rarely sees the light of day. If you've got something cool lying around, consider adding a few shots to this pool (Anonymity will be granted, if desired). Because sharing is caring.
