The new shirt, promptly named as "Kinkdom", was a rendition of Feng's Kinkdom Tower, a sketch which he did during physics class in 2003. The Kinkdom Tower was also used as the official cover art for Feng's demo album and has a tribal-house track "Kinkdom-Variations" produced specifically for it.
Here's a quick preview of the shirts:
