A euphoric sense of being overwhelmed by the convergence of technology. Feeling the vast intersection of systems underlying something deceptively simple (like a cellphone).
While we were talking about that restaurant on the phone, I looked it up on Yelp, flipped over to Google Maps, got my GPS coordinates, and found out I was standing right next to it! Spooky! I got a little synergasm from that.
