I've been thinking about creating some fun, novel market pegged assets, and I'd like your feedback:Brownian motion
This is a random walk, priced between 0 and 1 BTS. This would allow gamblers to use the bitshares wallet without modification to bet their BTS on random chance using the existing market mechanisms.London temperature
Feed price tracks the temperature in London in real time, again priced in BTS (fahrenheit so we don't have less than 0 - could use kelvin, of course) . At first glance this seems absurd because it is largely predictable, but I think this could lead to some very interesting behaviours.Bitcoin hash rate
Feed price tracks the bitcoin hash rateGames100 index
Tracks computer game sales for the top 100 computer gamesFilm100 index
Tracks film sales for the top 100 grossing films
The last couple might be hard to get decent data from, but the first lot should be a breeze. I'd love to hear what you think about this?
