Since 2020, I have been designing t-shirts for the French charity event SpeeDons, raising money for the NGO Médecins du Monde. It consists of 3 and half days of non-stop speedrunning video games on stage and streamed live on Twitch.

The event has been spearheaded by French Twitch streamer Xavier "Mister MV" Dang. He was known earlier in his career as a speedrunner himself and being involved with the Games Done Quick community, he brought his experience to build SpeeDons with Médecins du Monde. In only 5 years, SpeeDons grew quickly and went from raising 614K€ the 1st event to 2,231,146€ (from which about 500,000€ were raised through the t-shirt sales during the last event) in March 2025.
