I like baking Sourdough breads.
My favorite breads are rye breads with caraway and coriander, but those are hard to come by in shops in Switzerland. The pictured bread was my second attempt at making one on my own.
There are some pretty good resources for baking bread on YouTube, for example Alex' Non-Bakers Guide To Making Sourdough Bread. For a less involved recipe, I can recommend this Paderborner Landbrot recipe (German).
Knuffiworkout is an app that I wrote to track my workouts. It uses Flutter, a great reactive framework for writing mobile apps in Dart.
You can get it on the Play Store or take a look at its source code on GitHub.
In 2016, I spent some time playing around with Sonic Pi, a nice little program that lets you script music in Ruby.
The resulting album is called Sined Distance Functions and it's available on Bandcamp and YouTube. The source code is available on GitHub.
In 2014, I wrote my master thesis at ETH on adapting parameterized 3D models to 2D sketches. Afterwards, I did an internship at Disney Research to work on what would after some pretty cool improvements by Fabian Hahn become a paper on sketch-based posing.
The awesome dragon model is by Maurizio Nitti.
Oneiroi is a game for the Xbox 360 I wrote together with Aniruddha Loya and Tim Grabowski in the ETH Game Programming Lab 2013. There's a trailer video on YouTube!
In late 2010, Rudolf Schreier and I wrote a Fondue Cheese Simulation for a course in physically based simulation. We won the best course project award :)
I wrote my Bachelor Thesis in 2011 about making SPH simulations fast, reducing the neighbor search time by more than a factor of 3. As a result, we were able to animate millions of particles as in this waterfall or this town. The renderer was written by Daniel Zimmermann, the initial codebase was provided by Barbara Solenthaler, my thesis supervisor.
Liquor Box PC
I bought one of the first Intel Atom boards in 2008 for the cuteness factor. As I didn't want to buy a case I took an old wooden liquor box, trimmed it to the correct size, added a new lid, and installed the PC inside the box. It's not in use right now since I have a Raspberry Pi which can do pretty much the same with far lower power consumption, but I still like the case.
Homebrew Kombucha! :) This is pretty easy, if you have a starter culture you just have to add it to very very sweet, cold tea and wait for a week. The culture itself looks pretty disgusting, though.
Knufficast was an Android podcast downloader and player ("podcatcher") that I wrote in late summer/early autumn 2012 in the wake of Google Listen being discontinued. The source code is still available on GitHub, if you really want to dig into it.
