Great, please consider sharing it if not similar to existing libraries
(such as FakeSmile [1]). :-)

Updating this number of objects shouldn't be a problem. Of course this
will depend, as far as I know, on a number of parameters: the
complexity of the objects, the complexity of the canvas around them
(which may required more repainting whenever the objects are changed,
etc.).

Using "setInterval" is not recommended due to a Firefox issue [2]. A
script animation study was recently published [3], and discussion is
being done through a thread [4] in the Yahoo's SVG Developers group.


Hope this helps,
