Well actually I said cash, but this kinda thing (kick starters etc) can be about more than cash. Shows if there actually is interest.But as @pawlini said, as if Tim doesn't have the cash to do it, haha. Unless, he is giving a fair amount of the cash and the extra 37k they need is just because they legitimately don't have it. I doubt there will be a lot of donations though ...
Also - 250k doesn't really go that far these days. Who says Tim can afford it?
