Ryouko is no longer updated and has been succeeded by Nimbus (http://qt-apps.org/content/show.php?content=167467).
Ryouko is a simple PyQt4 Web browser. It was originally designed for Linux, but there is now full Windows support, and it might work on Mac OS X as well (however, this is completely untested). Ryouko was coded purely for fun, and is currently missing a lot of features. Therefore, it is *not* intended to replace your default Web browser, nor is it intended for serious usage or people who need a stable, dependable, and fully-featured program. However, it should be suitable for very basic Web browsing.
