The cab with the Thundercats artwork was built by Rasmus Kønig Sørensen. He kindly made his plans, CPO artwork and marquee available for download, so others (like me) could build the same cab. The image I posted was one such example of someone who has built the same cab, used his marquee and CPO but has different side art.
I am trying to track down whoever made this particular variant as he seems to have squeezed in a trackball and I wondered how that went, as its a 2player cab thats only 60cm wide.
