Couple months ago my friend Owen approached me with this project. It was based on the great work of his harpa pong last year. The basic idea is that they turned the facades of the Harpa concert hall in Reykjavík into a huge canvas by putting a led light on each window. Last year they created a pong game on this enormous canvas that user could play with their phone. This year during the Sónar Reykjavík 2015 they want to put some audio visualisations of the music of the main stage on it. And my friend Owen asked my if I would like to make one visualisation to it. I was really excited about the idea and I said yes right away, and then here comes the challenge : there’s only about 400 pixels per facade. So how big exactly is this canvas ? about this big : Just that tiny thing in the centre.
This is definitely the smallest canvas that I have every worked. I’ve been used to create visuals on a big canvas but now suddenly we only have 400 pixels to make visuals, that’s a whole new challenge to me. At first I was testing with basic geometries such as lines and rectangles. But in the same time I was trying out some ripples for other projects and then I was wondering what will happen if I put the ripples on the canvas of this size ? will it still be recognisable ? This is the ripple I made :
When there’s a beat it will trigger a wave. In the fragment shader I add all the waves together and based on the height of the map I mapped it to different colour which I get them randomly from ColourLovers.
So that’s my contribution to this project, you could check the live demo here :
Again thanks Owen for inviting me to this project. I am really proud to be part of it, and also I had a great time to create visuals and play on such a small canvas.
