I was checking out some syntax on dokuwiki’s website and suddenly a duck appeared from the right hand side. When I hovered over it, I got a web browser crosshair. When I clicked on it (bang), a bullet hole image appeared in the web page and the duck (quack) fell to the bottom of the browser window.
I didn’t see it blogged about yet so there ya go. Techcrunch has a good wrap-up of 2010 april fool’s jokes. This year didn’t seem as big as last year’s.
