1) buy property on which to build a sensibly-sized/priced house, but with my own 1st-rate well/septic system, geothermal heat, solar+wind generators... never pay another utility bill again! (Heck, put up a tower on my property so they pay ME for rural internet access!)
2) Rebuild my music studio in a soundproofed room! Not insane, but $10,000 worth of good music equipment and software! (My dream studio! Ahhhh...)
3) Manage the money for long-term savings/earnings.
4) Couple sensible family cars - one for the family (minivan) and one/two small cars for me/wife to buzz into town in. Electric or super fuel economy. Screw fast cars - that's just stupid. That said.... those Mini Coopers may not have the best mileage but they're nifty. So I'm not TOTALLY sensible...
