DMC makes a set of flat controls under the Creative Commons license. You can download from their website.

For those interested, I posted this idea in the exchange here.

I like to use a mix of system controls and drjdpowell's flatline controls (especially for graphs or buttons with a nice graphic).
As a side note, once you have System Controls 2.0 installed it will show up on quick drop. So once you press ctrl + space to open quick drop, you can type in "System Numeric" or "System XY Graph" and it doesn't feel disconnected at all.
