A Re-Purposed Rug!
In this, a carpet becomes a rug! This cool decor item is a real piece of history that you can own. A Segaworld in Japan once had this pattern you see here as the carpet. A wall-to-wall covering that, in arcades & casinos, is traditionally quite a busy design to keep you looking at the games instead of the floor. However, such items don't last forever, even if they're industrially designed....

like this one was. When that happens, they're usually stripped out by a company/rolled up and taken away to the recycler or the dump, then replaced with something else. However, a better way to recycle is seen right here! Take the good portions of the carpet, cut & trim them, and create way cool rugs! With the amount of square-footage that the original had, you could get very many 'room type' little rugs out of it just like this. So, it was wise to not throw it away.
This particular pattern has some 'casino night zone' type patterns of dots, Sega logos, and the same Sonic classic stock art repeated all over in a way that makes it contrasty (Sonic is bright with whites, yellow dots are around, and a dark background with random red blobs) The re-finisher has added fringe & sewn the borders to prevent fraying.
This one is no longer in Japan, and was bought outside of Japan as well. It is likely there are quite a few of these, but still far less than if it had been commercially produced. So, a rare item.
It's a piece of history! Owning something from a place that no longer exists (ex. a closed Segaworld) or of something that was somewhere famous, but got replaced (ex. classic Sonic) is extra special.
