50 winners have been selected for the first Google "Android Developer Challenge", and it was great to see the range of applications entered - wikipedia/map mobile mashups ("Wikitude"), consolidated virtual presence management ("Sustain"), pervasive gaming ("City Slikkers") - it's in there. And more.

And for your download pleasure, here's a nice, simply formatted .pdf of the winners - with images and explanations. Download AndroidApps.pdf
It's worth reviewing to get a look at what's coming next...
