Blockee is a web app that lets you visualize improvements to your block.
It came about during Labs Fridays* while I was a 2012 fellow with Code for America.
Blockee was built in collaboration with Jesse Bounds, Nick Doiron and Serena Wales. Try it out at blockee.org.
*Lab Fridays is based on google’s 20% time. It’s time CfA fellows are given to experiment with emerging technology and any ideas we’re excited about whether they are or aren’t practical.
