Hi! I’m Mathias Berg Rosendal (he/him). My username “rum i rum” is my Danish play on words for “room in space”, an analogy of the connectedness and joy that I felt radiating from my monitor as I in 2026 discovered the indie-, garden-, retro-, neocities-, smol-web and more; the beautiful creations making the web feel alive and genuine to me once again; the joyful rebellion against enshittification!

I’m interested in music production, programming, gaming, 3D modelling, photography, the economics of the energy transition and whatever rabbit hole keeps me up at night recently. I’m also an engineer, researching sustainable energy systems at the Technical University of Denmark.
