Urban trees

Mike's idea. An app which lets people geotag trees and the tree's health status.

I see lots of benefits. People would feel more involvement with "their" trees, and local governments could better visualize/optimze their urban forestry.

See also Natalie Jeremijenko, who proposes small urban actions which collectively have a huge impact.

guess the mashup

Fidel had an idea which went viral, using a MCMC language model to mash up different celebrity twitter feeds.

Do the same, user inputs a twitter stream, the engine mashes it with someone else, and you have to guess who (from a list).

Points and high scores.

Some app ideas

I.P.  dog-based social networking tool. Users p to leave a message, and sniff to read messages. Messages show user id, status, and a word cloud. Messages fade logrithmically


Augmented Reality Pac-Man. Uses googlemaps to play pac-man in real life on city streets. You choose bike or walking mode.

Hammer. An app to let you use your phone as a hammer. Not for the gifted
