Here are some of my contributions to the demo scene. Enjoy!
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: Read more.

llbit and I made a game.
It started out as a weekend project, but we threw in a couple of more days of
work to brush it up for the Game compo at Revision 2013, where it placed
2nd. Read more.

At Dreamhack Winter 2004 there was a surprise compo
(called the fast music compo) in which one had to write a piece of music
using only the default set of sound samples shipped with Windows. Read more.

Parallelogram is a demo running on the Commodore One extender
board, which contains an Altera Cyclone III FPGA and an SDRAM chip. The logic
design was made from scratch, including a homebrew CPU, FM synth and blitter
with pixel shader support. The demo won the wild compo at Revision 2012. Read more.

Phasor, like Craft, is a demo running on a custom
minimalistic ATmega88-based demo platform. But it generates a composite video
signal (PAL) instead of
a VGA signal. Read more.

I am very grateful to Barta Zoli from Hungary,
for building a replica of Phasor, making
a high quality video capture and allowing me to share it with you on this site
(and on youtube). Read more.

This is a simple but very useful tool for C64 demo
coding. It's a grid, 63 squares wide, that you print out on paper and draw
instructions on. Along the top are helpful reminders about which clock cycles
are involved in various effects, and which ones get stolen due to badlines
and sprite fetches. Read more.

Spindle is an integrated linking, loading and crunching
solution for C64 trackmos.
By hiding the details of the storage model, it allows the demo coder to focus
on effects, transitions and flow. Read more.

Normally, when you create a chiptune, you start with an
existing chip (such as the SID chip or
the YM2149) and write a tune for it. We decided to start from scratch, and
create a chip and a tune. Read more.

Turbulence is the successor of craft. It's a
microcontroller demo based on the Propeller chip from Parallax.
External I/O consists of stereo sound (at line level) and a VGA signal.

On this page you'll find the complete source code for
Turbulence, as well as a general overview and
discussion of some of the techniques I used. Read more.

This is a comprehensive visualisation of the behaviour
of the VIC
chip. It is quite handy as a reference when coding C64 demo effects. Read more.
