Ok, I'm sticking my neck out here and hoping for once I got something right.

Remember the HDR stuff from a day or two ago?

Well, I remembered one of the Chromasia tutorials talked about conversion to grayscale and it got me thinking...

If you'll excuse the pun, this picture floats my boat.

(The conversion here was performed using photoshops lab colour mode. the original plan to use the channel mixer worked well, but this seemed a little less contrasty and a little more light).

I'd put the process to convert this here, but you should really just check out Chromasia's tutorials as they're better than anything I could write.
