What I offer

Interactive Experiences

Using apps, internet and beamers, I create multi-user realtime interactive experiences for museum exhibitions, musical performances, theatre performances, festivals and more!

Earlier work

Het Kabouterspel

Interactive Social Game

Oh No! Your little gnome needs help! Due to a terrible mistake at the landromat, all clothes have been mixed up! It's your mission to trade clothes with everybody you see to help your gnome get dressed.

A interactive, social game. Using your smartphone, you are challenged to meet new people and trade virtual clothes. A beamer is placed where people can chat and write requests for clothes.

I'm more than happy to demonstrate this app in real life!

Hello, my name Mark Marijnissen,

I live in Nijmegen, the Netherlands.

I have been programming since I was a little kid. It all started in Logo. Then I moved on to Visual Basic. By the time I was twelve years old, I created a professional website for a friend - it was still HTML and animated GIFs those days :) In high-school I programmed things such as Blackjack on my graphical calculator, and after that I picked up Object Oriented programming in Delphi.

Now, I have a bachelor in Artificial Intelligence and I am working as freelance app developer.

But my life is more than app development. I like to create music (using keyboard, guitar, ableton push). I used to paint and draw, too. Because I am so fond of creative experiences, I enjoy collaborating with performers and artists.

I love the clarity and calm that mindfulness and meditation give me. I'm creating an interactive meditation app, and sometimes I guide a meditation at a local meditation group.

I like to practice non-violent communication to love and connect with the people around me - I am hosting a practice group in Nijmegen once a week.
