This screenshot shows the first version of Towel available from CVS, running on Matt's GNU/Linux box on the 19th of November 2002. It's much prettier than the previous screenshot, and there are also lots of extra buttons - almost all of which actually work.
It's playing Ogg Vorbis music again, largely because most of Matt's music is in that format.
For the curious, the window manager is Metacity 1.2.4, the GTK+ theme is Bluecurve, the widget font is Luxi Sans and the Metacity theme is a customised version of Bluecurve which Matt will be making available shortly. The Linux distribution is Gentoo Linux.
