Ooo someone mentioned kicadocaml!! If it is actually being used (even
for a trivial thing?) I'll continue to develop it (well, I'll probably
continue to develop it because I'll continue to use it). FYI
kicadocaml does use vertex buffer objects, but they are *not* in
graphics memory, unfortunately. I have a patch for lablGL (ocaml
opengl library) that adds this, but it's too messy to commit, and it
would make building the project difficult. Also FYI kicadocaml does
antialiasing if your video card supports it (most good ones do).

Just actually bought a pick and place robot for $100 off ebay. I
weighs ~1000 lbs - shipping was $378. Once I get it running I'll post
a video. In the meantime, I'm enjoying the PCB manufacturing/circuit
design conversation :-)

cheers!
