The price of ETH is going up because people are buying it to invest in the DAO.
https://daohub.org/ The DAO price starts to go up again on Saturday, so people are rushing in as the window closes. Right now the price is 1 ETH to 100 DAO. On Saturday the price per ETH will start to go up. It will increase incrementally every day for 10 days until it gets to 1.5 ETH for 100 DAO. So that's why the price of Ethereum is going up right now. I suspect ETH will go well above .03 before the DAO sale ends at end of this month.
