saw a talk by this guy once... amazing energy - sweetness incarnate.
on his website he has a list of ideas - in his talk he explained that this is his ephemeral to do list... things that have crossed his mind that might be interesting.
He happily allows and indeed is honored when someone else does one of his ideas.

kind of counter to the way art ideas are generally hoarded and held with a sense of almost selfish ownership.
but, ya know... the things we tend to hoard are the things that most freely slip out of our lives...
