The mystery button: a dynamic HTML demo

Most links point to pages, but some are portals into an unreal world: like the Mystery Button

CAUTION: Development of this button (Aug 2008) inadvertently caused a plague of blank pages in the Opera forums and also wiped out my blog; details here. Some effects were longlasting: for 16 months, one couldn't access Page 2 of this blog, or the archive - they came up blank. The devs recently (Dec 2009) fixed that - but you might want to save any valuable data to removable media before trying this puppy...

Note: doesn't work in Internet Explorer - it uses black magic, which Explorer doesn't support.
