Over the weekend, the largest US anime and cosplay gathering in the US took place, Fanime. One of the biggest parts of the annual get together is the Masquerade and one of the biggest stand outs from this year’s masquerade had to be the Portal stage performance.

The on-stage demonstration of Aperture Science beats all the recent online fan vids in my opinion because they didn’t have special effects to fall back on like the online ones. What you are seeing here is pure creativity… and honestly, a little bit of old school vaudeville.
