Just had a look at the archive myself, it's looking quite good/there's a lot of good and unique stuff there! I'm glad some people are making preservation efforts towards themes after the Xbox 360's Marketplace shutdown nearly a couple years ago now. On a slightly different note, I especially liked the themes during the Blades era, as I liked how they changed the background of each individual Blade (apart from the Marketplace Blade usually) - you still see them in newer versions but only in a specific menu, not all easily at once - and they even changed the guide background which is a nice touch.
