Subsequent Events [Abstract]
Subsequent Events	11. Subsequent Events During April 2013, we received $3,000,000 in cash from a private investor as the second tranche installment of a sale of common shares and warrants under a Stock and Warrant Purchase Agreement. These condensed consolidated financial statements were approved by management and the Board of Directors, and were issued on May 10, 2013. Subsequent events have been evaluated through that date.
