Flash is officially dead starting today, but I noticed the SWF file above was still online, so added it back as an attachment. It's a cute animation that even William Tell might appreciate.
Interestingly, I can still get Flash games to play in Chrome merely if I click to give them permission. But probably at some point, maybe with the next Chrome update, that will no longer be allowed. In which case one can use a dedicated player, instead.
Despite all the concerns about security, I doubt there's really any risk in running these older games and animations, even with obsolete Adobe players. I'm thinking fun stuff like that would not be a likely route of attack, and that it would moreso be invisible Flash applets at sketchy sites. Even so, after 20+ years of using and reading about Flash, I've never really heard anything about common Flash applets being unsafe in actual practice.
