Do you remember the Season 8 King of the Hill episode "Ceci N'est Pas Une"? In that episode an art store clerk in MacMaynerberry tries to sell Hank a hologram while saying, "Washington. Hitler. Washington. Hitler."
I recently came across the YouTube video below. It's not lifesize like in the animated show and I suspect it's a homemade lenticular prop. Whether or not my guess is correct it's pretty good art. It is on the Darren Toth YouTube channel.
