I hope you'll enjoy the video as much as I enjoyed making it! There are many little details that I'll let you discover on your own.

A Mind Is Born (2017)
Making a demo in just 256 bytes would be a formidable challenge regardless of platform. A Mind Is Born is my attempt to do it on the Commodore 64. In the absence of an actual 256-byte compo, it was submitted to the Oldskool 4K Intro compo at Revision 2017 , where it ended up on 1st place.

Safe VSP – 30 year old Commodore 64 bug demystified (2013)
I contributed this one-filer to the C64 Demo compo at Datastorm 2013 . It ended up on 7th place, which I consider quite good for a technical proof of concept.

Reverberations: An 8-bit approach to J.S. Bach
The toccata is perhaps the most well-known work in the entire organ repertoire. Like many toccatas, it is probably a transcribed improvisation. It has been postulated that this was a test tune that Bach would play when trying out new organs. That would explain its crude character and the various hops between heavy…

Kernighan's Lever
Everyone knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it?

Assembly Routine for Realtime Decoding of Floppy Data
The little routine presented here is, with all due humbleness, hands down the best code I ever wrote. It is esoteric and might not appeal to the masses, and it certainly has no commercial value. But in terms of personal satisfaction at a job well done, this is about as good as it gets. Here's why:
