About me

My name is Rolf Smit. I’m a computer science student, working and living in the Netherlands. I have a passion for programming, especially mobile development. Currently I work as a freelance app developer and I created some cool stuff you might want to check-out.

Besides hard-core coding I’m also interested in UX and design. In my spare time I like to photograph things, listen to music and scuba-dive.

Pixie Dust

Pixie Dust feature image Pixie Dust feature image

Pixie Dust is a special story, it originally started as a programming challenge. But after the first prototype it turned out to be much. Pixie Dust is a 2d real-time sandbox game written in mainly C++. Players can mix up elements and see them: grow, burn, vaporize, explode, dissolve, you name it. It’s literally possible to create wicked chemistry experiments or just blow everything up. Pixie Dust has become quite popular, with over 20.000 downloads in the first six months. In the future I would like to add more elements, achievements and online sharing.
