I was just thinking that I used to really like the CDE Motif theme, but after looking up screenshots I realized what I was actually thinking of was Java's cross-platform "Metal" look and feel. I liked how MDI windows looked like they had knurled tool handles for the title bars. I liked the little notches on tab panel selectors. At the time, I liked it because it was novel compared to what I was used to (Win9X), but now I like it because everything looks like it does something. Now that I think about it, Motif is the least favorite of any DE theme I've ever used.
