h1CSS Fisheye/h1
pRun your mouse over the text below to see the effect. It's implemented using
CSS and Javascript. I got the idea from this a href="http://www.samuelwan.com/downloads/com.samuelwan.eidt/fisheyemenu/FisheyeMenuDemo.html"fisheye
demo/a, which uses the effect for menus, but is implemented using Flash. Laur
at a href="http://www.grapefruitdesign.com/"Grapefruit Designs/a pointed
to the same technique implemented as a Java applet at a href="http://www.cs.umd.edu/hcil/fisheyemenu/fisheyemenu-demo.shtml"HCIL,
Univ. of Maryland/a, and suggested that the idea had probably been around
since the 1960's. It also seems that Ted Nelson had described this and similar
techniques ("a href="http://xanadu.com/zigzag/fw99/billowing.html"billowing
and undulating text/a") in relation to his Xanadu project back in 1999./p
pMy a href="fisheye-old.html"earlier version/a only worked on Internet Explorer,
but the version here has been fixed for other browsers by a href="http://www.seairth.com/blog"Seairth
Jacobs/a. Also the previous version used a href=... to mark the lines,
the current version uses span i("for no particular reason")/i. /p
