[sdiy] SUPPER HAPPY SYNTH DAY!

[Rude 66]

cool, nate. now all you need is to find some way the school'll fund your diy
habit.. or get a 'student discount' from the manufacturers..;-)

i remember being equally happy when my highschool english teacher told me i
could use ian curtis' Joy Division lyrics on my reading list for my english
exams. unfortunately it didn't work for German with Kraftwerk lyrics.. ;-)
