Prezzle (fo'shezzle) does virtual gift wrapping and associated gift interaction.
It's based on the premise that the down side to sending online gift certificates and virtual gifts is the recipient doesn't have something to hold, shake or otherwise bop about =D
Watch the demo. I think they've changed things a bit; everything's on the main page.
You can't slap the recipient for shaking it too hard, but that's coming in the next release.
Right, Dan? XD
