Sebastian Hällman

Engineer in Media Technology

Hi there!

My name is Sebastian and I am a Media Technology student with the expected graduation in the summer of 2025.
Technology has always been my thing, using it to create interesting experiences and useful tools for the daily life.
But talking about it would be long and boring, why not look at them?

Gnome Huntclose

Gnome Hunt is a multi-platform hide and seek game where the hiders play as garden gnomes by connecting to the game through their phones while the seeker shall find and shoot them in VR.

Winter Windowclose

Winter Window is a virtual reality experience that puts the player in a snow landscape where they can construct snowballs, throw them and build snowmen. To make it more interesting for the spectators, they can move a physical camera around to change view angles of the virtual world.

I did the earlier version of the snow deformation shader that makes the snow deform when you interact with it. Anton later rewrote it due to performance issues. I also recorded physical sounds so the experience would be more immersive.

    Voxel terrain generatorclose

    As a long-time gamer, I wanted to re-create a simplified version of the terrain generation. With the use of layered perlin noise, I created a simplified terrain generator with 3 biomes and a ground level. I also added a settings menu so you could play with the parameters.

    Do you know how popular movies are?

    GuessWhat: IMDB rating quiz gameclose

    In the game GuessWhat, the user is given two random movies from IMDB and should choose the higher rated movie. You play infinitely until you get the wrong anwer. There is a global leaderboard to compete in.

    I worked mainly with the design along with Saquib, but I also worked on the game loop, i.e the timer and the API calls. I also did some work on the authentication with firebase.

    Since the course paid for the API and no longer works, the game does not work. The site, however, is still deployed on the web.

    D1sabl3dclose

    When the covid-19 pandemic started and everything was in lockdown mode, my chess club started to participate in online chess. I decided to start streaming them just for fun on Twitch. I never expected it to grow anything, but I continued and today I produce chess content weekly on the most common platforms, participating in charity events such as Musikhjälpen yearly and trying to continue my growth. I was also invited by Tele2 to Dreamhack Winter 2024 for a guest talk about internet safety.
