We did some signal processing to enable this web app that teaches dads to speak to their young kids in “baby talk”. This one was coded up in C++ and converted to js using emscripten.

I helped out with the tech to turn a huge office building into a music sequencer! Check out this pretty promo video:

We worked with We Do to build a smart cat collar that tries to translate cat language to english. The whole thing is a bit tongue-in-cheek as you can see in the video below, but the thing actually works, even though we only built one copy. You can even see me in the promo video making cat noises…

We developed a state-of-the-art automatic DJ system for Pacemaker so you can spend your time on more important things. Go get it for your iPhone & iPad, it’s also FREE!!!

We did the synth for this lovely app. Go get it, it’s FREE!!!

Here is the latest iteration of my as yet untitled interactive art piece. A sensor reacts to body movements, which are translated to colors in software and projected onto the bodies in real time. Future versions will also react to incoming sound. Stay tuned, and contact me for more information on this piece.

This video was shot under the Liljeholmen Bridge in Stockholm, Sweden on September 8, 2012, where the piece was shown as part of John Essing‘s “The Dark Light” release party.

This year I’ve made a “conscious” x-mas song for you all to enjoy. It is a dwelling on one of the more moronic topics in the 1984 hit Do They Know It’s Christmas by Band-Aid. Listen, take heed, and become enlightened!

As an experiment, I have beset myself upon producing a finished iPhone-app with only 24 hours of work, including everything from idea musing to writing this blog post. To save my own sanity and health, these 24 hours were spread over a 2-week period (including the 5-day App Store review process).

The app is called Vocal Shapes and is a visualizer for monophonic audio signals such as your voice or a musical instrument. Here is a quick demo video:

Here is a breakdown of how the hours were spent:

Idea	1 hour
Audio Signal Processing	2 hours
OpenGL graphics programming & design	4 hours
Splash Screen Artwork & Animation	3 hours
Fine tuning of processing & graphics	3 hours
Testing	2 hours
App Store Submission	3 hours
Promo Song & video	3 hours
This blog post & product web page	1 hour
Sum	22 hours

 

So, 2 hours remain, which I will probably spend making another nice demo video. Lessons I have learned so far:

• Simple apps require dramatically less development time
• Simple apps are more fun to develop
• Even the simplest apps apparently get downloaded by some people

NOW GO TO THE APP STORE AND BUY THE THING FOR $0.99!

Note: this app is no longer available, I haven’t had the time to redo it for newer phones. If I were to resurrect this, it would probably be as a web page, using WebGL.
