What could I buy? $17,000 to spend

Donate to crowdfunding projects and become a sponsor of stuff like hover boards and holographic displays that are still in the beginning phases. I'm sure that if you become a sponsor, you would get demo's and prototypes of whatever you support in the long run. Otherwise buy a fish tank? Pets for your home? Solar panels for free energy? Waterbed? Jacuzzi? If your into poker then join the next WSOP? Buy a hobo a beer and some jerky?
