I've just picked up SFML today for the first time, with barely glancing at the docs I was able to get a working space invaders prototype game done in a day. Using the Dec 17th nightly for VS11. Everything was right where I expected it to be in the OOP style, and everything I did worked great and was
very easy to work with. Thank you for the hard work that has gone into this, and the free, even for commercial license!
