Colorspace 1.7
The color wheel is by Xoetrope (Luan O'Carroll), the color picker is from Quaqua (Werner Randelshofer) and the LAF is a customized version of Substance (Kirill Grouchnikov)
I also use BSF, Rhino, SwingX and SwingX WS. Apache logging and JDIC are there for dependency reasons. Icon sets are Eclipse and Tango.
