The Foundation for the collection of antimatter.

A community art center. The local one here burned down 10 years ago & nothing ever "fully" took it's place. That type of outlet has really suffered since. Maybe I'm crazy but I can even feel the void even in the daily attitudes of the locals.

Video game development

I would like to turn my back yard into a community garden. I just don't have the funds and energy to clear the land and upkeep the garden.

A cafe / cat adoption center combo. The cafe would have some of the more friendly cats hanging out, and then the more shy cats would have their own building off the cafe.

Co-op Brothel?

I would open a chain of old folks homes geared specifically for dorks, and do it up right. Top of the line medical care combined with wings that look like Gondor, the old Battlestar Galactica set, that shit would be gold. If anyone steals my idea, hook me up with a room!

I'd like a little restaurant. Nothing fancy, just a little burger joint.

I would start a medical marijuana growing and distribution company

My first thought is a chain of non-profit grocery stores.

Fair trade, recycled and all natural store. I had a business called Green Lady but sold wholesale to others-I'd have my own shop this time.

I know they say never make your hobby your job, but I still think the right answer here is "pornographer."
