What's this?

I have done a lot of PCB design and part ordering lately and I am waiting for packages to come every day.

I got some PCBs in the mail today. They're a crazy color, almost white. I stuffed all the parts I had around into the prototype boards. Now I have to wait for the pots and last few other parts to get here. This is going to be a lot of work, but I'm looking forward to it.
