Google Maps Pac-Man made my day. I jumped around the world trying to find some complicated layouts. Here's a few I came across that were fun/frustrating.
Near Big Benhttp://goo.gl/1cVELy
Taganskaya Square, Moscowhttp://goo.gl/kQCcM9
Arc de Triumph, Paris - apparently Google likes this one as well, since there's a giant pacman icon already on it.http://goo.gl/R9OLrU
And since I live in the Burgh, here's Point State Park, Pittsburgh, PAhttp://goo.gl/tuuOAt
