If you click on the Picture of the Day label you'll be able to scroll through some great Warhammer related images, all at once.
I had remembered awhile back a bunch of top notch painters all entering Primarchs into the Golden Demon competition. I don't *think* this was the one of Horus, and that's why it cought my eye. But I could be wrong.
Either way, still awesome, and it seems to be part of a diorama that's based on a famous picture that we all know and love. -Enjoy MBG
