Any good replacement GUIs for WinXP?

[Cheetah Designs]

Hi there,

I was wondering if anyone knew of any good replacement GUIs for Windows XP.

I am talking about the ones that replace the Explorer.Exe

I know of objectbar and litestep, I was wondering if anyone knew any other good ones.

I was thinking of making one myself and wondered if anyone had any good ideas of what could be included.

So far I have: console type application where you can do written commands, quick search (may even have own indexing system),show drives (which are ready) on desktop.

Thanks in advance for any responses.
