Here's the new BitShares Desktop Wallet, brought to you by the CITADEL.
Some tech details:
it's written in python, and is heavily based on xeroc's python-bitshares library, it uses QT4 for the UI, so it's easily portable to OSX, Windows and Linux. I'm providing builds for the OSX and Windows versions myself, and the linux guys are supposed to use the source tarball.
Please do not hesitate to ask any questions, and report bugs; this is a very RAW first version and we expect lots of failures and problems, to be honest.
However, it already has quite a lot of features, including support for BitShares BLIND TRANSFERS (yeah!).
