Jolly cool: before Google takes it off their page, which clever bugger can make a copy of the underlying code and make it available via a hidden button on the Frost* page?
Google does archive these doodles, but it's not obvious whether the interactive ones work. For example, the recent lovely one commemorating Gideon Sundback's anniversary and his invention of the zip no longer functions (sadly):
http://http://www.google.com/doodles/gideon-sundbacks-132nd-birthdayOr am I missing something? :?
Edit: I noticed that when I opened the Moog doodle with my default browser, Safari, it has the blessed cheek to say "Upgrade to a modern browser and see what this doodle can really do", where the first part was a link to Chrome.
So I dutifully fired up Chrome to see what else it could do: unless I'm missing something (again), the answer is nothing. In fact, Chrome is
less capable, because you can only play the synth via the mouse with Chrome, whereas Safari allows you to use the keyboard. Pah ... !
