I have no experience with animated GIFs: How do you control the
blinking?  There must be an easy means to stop animation and clicking
between the states (from within the browser, of course).

Yes, sounds useful.  Can such a feature be provided with animated
GIFs?

Looking around it seems that sprite PNGs are an alternative to
animated GIFS, where the various sub-images are accessed with
JavaScript or CSS (cf. property `background-position'):

(and look at the `further reading' section on this page).

Have the sub-images side by side horizontally would automatically
provide one of the modes suggested by Arvinder...
