And I that thought that the days of the gaudy "spinning flaming logo" were over. To my knowledge I don't know of any WYSIWYG application that writes .js/CSS animation code. Add to this that HTML5 is a still a DRAFT and am afraid few coders would venture to develop an app for standard that isn't finalized yet. Also, that was the point of getting away from Flash was to make CODE /CONTENT meaningful an accessible.
HOWEVER... if you are already somewhat familiar with HTML ( any ) and CSS3 there might be a way of doing this w/o a program.
1) think graceful degradation. A fall back for browsers that don't support HTML5 and CSS3 ( you would have had to have done this anyway)
2) think accessibility ultimately it should just degrade to text ( screen readers cant see funky spinning logo.. they should just read out the company name)
<h1><img classs='logo' src='logo.png'> <span>L</span><span>O</span><span>G</span><span>O</span></h1>
3) use CSS3: [transforms and [URL="http://www.w3schools.com/css3/css3_animations.asp"]animations](http://www.w3schools.com/cssref/css3_pr_transform.asp). You can assign fonts, spin/rotate, translate any element with transforms; repeat, alter and delay movement. I realize it wont be as right brained as using Flash, but definitely not as left brained as .js
