Hi, my name is Per Gantelius and I’m an artist trapped in an engineer’s body. And vice versa. I do freelance software development work and sometimes design commissions, the latter often involving some degree of computer magic.

I channel my artistic tendencies at Perarnia and help build games and interactive experiences at Aesthetic Obstacles. Once upon a time I made an iOS app called Kaleidomatic. I’ve published a few open source projects, most notably fSpy. In the past I’ve also done some 3D modeling and animation.

My background is in computational mathematics, sound engineering and game development and my technical interests include real-time systems, digital signal processing, audio, 2D and 3D graphics and embedded programming, to name a few.

I live in Stockholm, Sweden and I’m always on the lookout for interesting projects and people. Are you looking for consulting services or someone to talk to about your weird idea? Drop me a line!
