I am pretty surrounded with technology. I work at IBM making software (although databases will never really be on the "cool" side of technology); I love to futz around with computer hardware and software; and I love to see new stuff coming down the pipe.
And then there's stuff that simply takes my breath away because it's so far beyond what I could ever have conceived as possible. Photosynth is one of those things.
Here's a couple of videos that show off Photosynth:
Video - from the TED conference: Video #1
Video - from the Photosynth team: Video #2
This is just jaw-dropping stuff and it will likely revolutionize photo sharing and taking, as Google Earth and Google Maps have revolutionized mapping.
