Bernie, Sebastian, and Yang are posing on the rolled-up Persian rug. I was doing lots of revamping to the network (behind me as I'm taking this photo) and I had moved a huge pile of debris off to one side, hence the rug rolled out of the way and the boxes of debris and so on).
The rug didn't stay rolled up for long, btw. I discovered that all three of these cats were sharpening their claws on the nap, which wasn't doing it a bit of good. There were little bits of rug yarns all over the place. I unrolled the rug asap thereafter.
