In 1989 and 1990, I produced a few ‘Amiga AV Demos’ with friends. I made the music and visuals and my friends made the software to play them as a visual ‘slideshow’ with music. One demo was used for five months to promote the Commodore Amiga in our local computer store.

The Commodore Amiga was not only great for producing music, but also a powerful tool for making images and animations. DPaint was a very fun and creative paint/animation program that I enjoyed very much. Digitizing (sampling) images was not possible yet.

Together with friends I produced ‘Amiga demos’. In the 80’s and 90’s there was a lively international Amiga ‘demo scene’. A scene of small teams that produced ‘demos’: self-contained computer programs that produce audio-visual presentations. The purpose of a demo is to show off programming, visual art, and musical skills.

I provided the music, images and animations for our demos and my friends created the software to run them together as an audio-visual presentation (a ‘slide show’). I used DMK or JtC as my alias. One of our demos was used by Game World, a computer and games shop. Our demo played in a loop in the store in the spring of 1990 to show off the AV power of the Amiga. This was my first public AV ‘performance’!
