Ok, let's start out simple. Buy 10 cows, 15 chickens, 1 rooster, three pigs, and one dog. Find a couple acres out in the country and get the foundation started on the farm house. Order up the solar panels and the "how to make houses out of hay bales" books and get reading. Come winter you'll have to live out in the barn with the cows but it'll be nice and comfy. When spring comes around sell a couple of the baby pigs and some eggs at the market. Invest the profit.
Wait 50 years.
Withdraw your $50 from the investment and purchase the Intel Pocket PC Camera or Intel Pro PC Camera. Realize you are 50.5 years late on the free software offer. Curse aloud. Exclaim it's not the destiny, it's the journey.
Find true joy.
