Mark is the developer of sIFR, which helps bring rich typography to the web. He’s also worked for Silicon Valley start-up JotSpot, which is now part of Google. In the past few years he’s worked for Xopus, where he performed crazy DHTML wizardry to create a friendly, browser-based, WYSIWYG XML editor.
Besides the purely web stuff, he’s worked on Physical Computing / RFID projects in both his spare time and as part of the PICNIC conference. He has also been a speaker at various events and conferences.
Mark is also involved in Toothless Tiger, a web freelance agency responsible for various fun projects in the Copenhagen area and beyond.
