I designed and distributed the t-shirts for the Computer-Automated Multi-Paradigm Modelling (CAMPaM) and Multi-Paradigm Modelling (for Cyber-Physical Systems) (MPM/4CPS) workshops organized by my doctoral supervisor, Hans Vangheluwe over his research career. There were inputs from many people in the design: Hans of course, Joeri Exelmans also gave inputs, the idea to have a rock-band like back-side was first discussed at the Ajaccio airport with (if I remember correctly) Hans and Julien Deantoni; originally, the tshirt was only in white but Thomas Kuehne asked for a black t-shirt, giving us the idea to also go black (which was ultimately more popular) as seen in the photograph below.
If you attended an event and want a t-shirt, just send me an email.
