If all the boring stuff is handled like speaking to a lawyer, hiring an accounting firm and then another to do audits on the first, and of course keeping it all secret.
I'd build my dream house. Nothing huge, but something with a really large pool--something I could realistically afford now but wouldn't be wise for me to buy. I'd set up my funds to pay out profits on investments and figure out with what I could do with that 'for fun'--might invest in some whacky projects or venture capital stuff, I'd go in expecting to lose it all but I would try to find projects that deserved a worthwhile chance, and which were run by guys who really busted their ass for their dream. I've also always wanted to travel extensively, so I'd do that.
Otherwise, the only really cool thing I've always wished I had enough to do is eat out often and tip the wait staff you see busting their asses really well, like a couple thousand dollars. Or do the secret Santa thing where I'd pay for random people's orders in line. Really enjoy the idea of making someone's day who is in that bracket of working hard but still struggling. I think I could have a lot of fun, for a long time with that (And would always try to keep it anonymous or it would ruin it...nothing worse than being asked to do it.)
