This was a Xen T-shirt around 2013-2014 (http://wiki.xenproject.org/wiki/Xen_Project_Swag#Hall_of_Fame http://wiki.xenproject.org/wiki/Xen_Project_Swag#Hall_of_Fam...) but it seems to be missing from the xen.org store unfortunately (http://www.cafepress.com/xen_org http://www.cafepress.com/xen_org) It seems simple enough, though. Make your own!
