Do you remember Shoes? It is a simple cross platform GUI for Ruby created by the mythical _why_the_lucky_stiff. Did you know it is still maintained? Shoes 3.3.4 runs on Windows, OSX, and Linux plus a few more variations like Raspberry Pi and FreeBSD. There are new widgets and features among the bug fixes. There is also a jRuby reimplementation of the original Shoes known as Shoes4. Start your exploration here and join the community on Facebook and Github.
