Web site design and implementation
Some of the web sites I’ve done since 1994.
Dubbeldissarklubben
This Swedish site has served the public with obtrusive movie reviews since 1999. For some strange reason there seems to be a lot of visitors with a love for Josh Hartnett. [1999]
Impulse
This site was created by me in 1994 to be the virtual home of demo crew Impulse.
Back then, the web was quite an empty place and this was one of the very first Atari related sites on the net. [1994]

I implemented the site in WordPress. [2013]

A small site to promote a club based in Örebro,
arranged since 1997 by Stefan from EBM band Spetsnaz. [2005]

Java 2D effects
A few examples of old-school demo effects, rewritten in Java for easy viewing.
The Blob
The physics idea of this emulation is based on simulated gravity acting on mass distribution. The effect is quite familiar to the old lava lamps, where the slimy material inside shapeshifts as a result of the heat. [2000]
Julia Morph
The Julia set has a close relation to the Mandelbrot set, since the Mandelbrot set is the set of complex numbers to which there are continuous Julia sets. This morph is created in real-time by changing the constant value in the iteration procedure. [2000]
CSS and JavaScript
A wretched hive of CSS and villainy.
CSS3 Wars

RGB Reine
Totally innocent here. In fact, this demo was made by the friends in New Beat Development as soon as they managed to get a paparazzi shot of me being high on caffeine in the middle of the night. [1996]
Generated nonsense
Gbg Ipsum
Content generator for Gothenburg language branch.
We have all seen the various “lorem ipsum” generators, but I felt there was room for one with the coziest language in the world. [2010]
