Project update: 27/1/2017
Since our last update, many things have changed. The Redmond and Longhorn Github repositories are now under the project's control, a new maintenance method has been adapted for XP themes (now a separate bunch of themes from the Redmond collection) and we've been polishing a LOT our macOS Sierra theme. The Android theme made it into final stage (available here), the Chrome OS themes are now organized under the 'Google Themes' page and an OS X Mavericks theme was temporarily available during the holiday season.
So, what could happen in this new year? The project will celebrate it's second anniversary - we'll have some surprises for our followers - and some other themes could appear, now that 'effective maintenance time' has been reduced with our new 'Modular Theme Architecture' used to create the XP themes. Options are: iOS theme, OS X Mavericks (add support) and a JDE theme (Java Desktop; no, I'm not an Oracle/Sun guy, I just like the overall appearance of it).
Update: JDE theme will not be produced after all
Maybe expect some activity on the side of Icon themes, as we've now got help to further develop the WinXP theme, and possibly the newly available Se7en Icon theme, so be alert! (Maybe B00merang Round will do a comeback too, just maybe...)
Meanwhile, we invite you to explore and enjoy our current artwork. Oh, and happy new year :)
