Window Maker was one of the reason why I decided to start using Linux back in 1999. I was running Windows 98 back then, and I was so taken by the style of the different window managers available for Linux. I marveled at how flexible Enlightenment looked and fvwm either looked like crap or like a work of art depending on the time the user spent in his configuration file.
But by far, my favorite look was Window Maker. I liked the large icons, the blocky menu, and the intriguing dockapps. After I managed to install Linux (that was a hard task for a 16 year-old who couldn't read English), I used Window Maker for a number of years. It was fast, it was functional, and it was really cool! These days I use LXDE with Openbox, but I'm always thrilled to hear about new developments in Window Maker.
