Bloody Flickr!

I just bought a beautiful new camera. I just saw THIS amongst clarice & ...'s excellent photos. Rollei makes a Minidigi twin lens camera.

I'll be honest. I never really wanted a Rollei, as the site claims everyone does. I don't even know what twin lens means or what they do, but suddenly I feel I must have this little piece of gold or my world will collapse around me. What the hell is this??
