The DAO is basically empty(extraBalance can't be moved at the moment), but tokens still exist and have a real value. Some people buy those tokens thinking they will get ~1ETH per 100 DAO tokens at the end of this. But 100 DAO tokens trade at 0.73ETH at the time of this writing. Couple days ago they were even worth something like 0.5ETH per 100 DAO tokens. I wanted to know how much are they worth in the real time without having to check their value manually too often so I created a Google Chrome extension for myself to help me with that. It is useful to me, may actually be useful to others too. Maybe it will help someone, so I am sharing it:

This extension shows 100 DAO tokens value priced in cryptocurrencies (ETH, BTC, USDT).
