Jesper reviewed FXRuby -- Create Lean and Mean GUIs with Ruby by Lyle Johnson and gave it 8 out of 10 horseshoes.

This book is about FXRuby, a library for developing GUIs with Ruby. ... The first part (chapters 1 to 6) is a gentle introduction to FXRuby, in which you build a simple photobook application step by step. The second part (chapters 7 to 14) is a more thorough overview of how FXRuby works and how to use all the different available widgets to build a GUI. [...] the book is useful for beginners and experienced users alike. For anyone who wants to create a good GUI for their Ruby application, I would recommend them to have a look at FXRuby and this book.
