Solomon Kahn was a fellow at the EJ Safra Center for Ethics Lab on Institutional Corruption. (His day job is at PaperlessPost.) As his project for the Lab, he built this supercool code for viewing and understanding contributions to politicians. There’s lots of great sites that do this, but the dynamics of Solomon’s UI is really compelling.

He’s running a Kickstarter to raise the funds to make the site perpetually available. The code and content will be freely licensed. If you can support it, please do.
