Thats a great idea Finn, I\'d steal that one, but you guys don\'t think big enough...
1) Get a space ship and do some exploring, preferably one that could actually make it to the next sun in a decent amount of time, but given thats currently impossible, I\'ll settle for a system ship to explore the solar system.
2) Buy an island, set up a new state, and get some sensible laws in place, create a perfect utopian state (well at least from my POV).
3) Buy land in various places around the world.
4) Build a castle (a proper one with moat, portculiis, dungeon etc.), live in it. Have SCA events there, jousts, feasts etc.
5) Setup a science foundation to fund research, and make myself a big lab, get some grad students and postdocs in and start actually doing doing all the research ideas I have that I can\'t get funding for. Base it somewhere near to a decent beach (pretty easy in Oz) so we can have some fun after work.
I\'d also do the whole investing, charity, buying new toys, family thing, but given that no. 1 would probably cost more than I have, I\'d need to find a way of turning that 1 billion into a few thousand billion.
Trevor, never stumped when asked what he\'d do if he won a million, the answer is always: \"A million is no way enough for what I want to do\"
