This is a screen from the Black Knight web page / gadget thing that Sega put up to promote the game. It was a website you could go to and sort of interact with if you waited long enough for it to load. They had "find the __", target practice (seen here) and other ways to interact with the content. It included some character profiles, & a win-able wallpaper as a prize (for finding 'rings' on the site). It also played music through your browser while you were at the site. It's sort of an "item" because it would dispense content & play games, but kind of not, because it was a page. Still, interesting enough to archive.

Spiral Knights is a game available on Steam. If you bought the game, & then spent 19.95 on "an energy pack" you would get the Metal Sonic inspired armor pieces you see here. They were a helmet & the body armor parts (represented as 2 disks there in the ad)
