Jason sent in this theme by Akakios on Themes4BB. It looked quite good so I thought I would mention it. The Icons overlap a bit on the zen menu but that is the only fault. I tried it myself and it looks good with many nature backgrounds that I like.
The top bar is nice and clean with a goldish-brown tint. The time is easy to read and has a simple blocky font. The custom icons really look great in this theme and match with the whole color scheme perfectly. The menu colors are a bit shocking at first but they do match the theme. I just wish they were a bit more subdued.
Check it out at this link on Themes4BB. OTA install only. Thanks Akakios!
