Check out this site from Pedigree in New Zealand:

It uses facial recognition software to match you up with a lookalike dog who you can then adopt.

Adorable use of technology combined with a philanthropic angle AND a play on words to boot? You had me at woof!

Sadly you can't adopt from the States (yet!), because I would totally take Holly home, even if we're not exactly twins.
