Flash

Adobe Flash is a beautiful sollution for creating graphical eye-candy or stable RIA's. I have used Flash for both and below are some things that fall in the first category.

• DYCP Nostalgia (August 2004)
  DYCP: Different-Y-Character-Position. A scrolling text in mid-90s Amiga fasion, written in Flash MX.
• 3D Textures (July 2004)
  Texture mapping on 3D objects in Flash MX. Source available.
• Dodecahedron (July 2004)
  Experiment with 3D in Flash MX. Source available.
• Magnetism (July 2004)
  Flash playdo. A Flash MX component version of a very old effect. Source available.
• Grow-A-Tree (March 2004)
  Experiment with recursive objects in Flash. Based on the fabulous levitated.net. Source available.
• Flash Photo Album (March 2004)
  A bunch of photos of Amsterdam thrown on a heap in a Flash photo album.

Pascal

When I had my PC in '91 I started programming Pascal right from the start and Assembly soon followed. These packages below are some of the things I made. They were made in Turbo/Borland Pascal, but it may be possible to compile under a different flavor of Pascal.
Note: these programs were mostly written before the age of Windows and might require a DOS-emulator to run properly. Also check /files/pascal.

• PD (Summer 1995 - Fall 1998)
  Personal Database: a freeware, public domain (open source), personal addresses database. Written in Pascal and Assembly with a load of functionality, including context-sensative help pages and pull down menu system.
• Signal2 (November 1996)
  Sound Recognition v2.0 is an instrument recognition application that was written for a school project that we aced. It has a nice fast implementation of an FFT and uses my gfxfx code to display sound waves and frequency graphs in real-time. Pascal source code and executables provided in the ZIP-package.
• Analyse (January 1996)
  Analyse is a small program to analyse data files of a physics spring system that I made during my studies as an improvement over the application the polytechnic provided. Source code, executable and data files are included in the ZIP-package.
• gfxfx2 (February 1995)
  Shareware package of graphics related Pascal source code, including 3d programming, image viewer, lots of scrolls and much more.
  (Note: addresses mentioned in the documentation are not valid anymore)
• Tempo Typen (December 1994)
  The Tempo Typen game implemented in Pascal, including source code and executable. Saves highscore.
• gfxfx (April 1994)
  I released a lot of graphics source code on Fidonet, written in Pascal and Assembly. By popular demand I bundled all the code and released it as gfxfx: Graphics Effects. This is that package.

C64 demos

Commodore 64 demos were a creative outlet, a funny way to show what you could create (as a team or on your own), a way to spend a rainy sunday, etc. The demos below were all created in 1988 and 1989 by a group called 'Cool Crew', of which I was a founding member.
These programs can be run in a C64-emulator. Also check /files/c64demos.
