YesWeCarve.com is hosting a “Pumpkins for Obama” competition to win an 8GB iPod Nano.
“Pumpkin photos will be evaluated based on a number of factors, mostly having to do with sheer awesomeness.” Download a stencil from the site, or free-form your own Barack O’ Lantern. Submissions are due November 2nd, and the winner posted at midnight November 3rd.

SocialThing guys were experimenting at FOWA with long-exposure photographs of iPhone air-traced images.
Found this link I Twittered some months back - http://tochka.jp/pikapika/ – PIKA PIKA uses Flashlights, and series of images as pseudo-animations. Also have presented internationally at conferences.
Super cool.
Ben and Joel – post your photos when they’re up!
There’s a Beantown event, if you are nearby and interested in the urban arts scene – I definitely recommend:Legends of Style (Boston) Urban Art Eventhttp://www.legendsofstyle.net/
