       | gets an image', 'gateware' to configure the fpga, and some python
       | scripts that read an image from the fpga and serve it as a web

       | Now there's a name I haven't heard in a long time. It's meant to
       | be a sort of digital Swiss Army knife, where you can connect
       | almost any digital interface to a computer and do basically
       | anything with it programmatically. I'll have to pick one up now
       | that it looks like they're released.
       | 
       | I'll probably still end up using an arduino as my one-off IC-to-
       | PC interface device just out of habit and not needing to read any
       | documentation, but I love the idea.
