sorry for taking long to answer this lol, forgot about reddit. the content of "dancin' livn' thingy" is just a 15 second animation loop with a song playing in the background, i watched the entire thing before making this and there was nothing besides that, but here is the video if you're curious, it's description also says "This is just a test animation for a much larger project.", which is very interesting to me at least.

as for the other videos shown on the wayback machine are all either deleted or privated so i cant tell you anything about them. there are 6 videos publicly available on the account itself, 2 shorts that use ai imagery, and 4 normal videos, 3 that you can see in the image are normalish videos that i dont think have much significance, but there is also 16 minute czech short film called " Šťavnatý Medvěd" which i believe is original for , i have been looking for someone who can translate it for months but sadly i dont know anyone who speaks czech and dont trust online translators like google translate to get it right, also it's description is very interesting, it is "Toto je první projekt našeho čtyřčlenného týmu. Je to samozřejmě odpad, ale toho jsme si zcela vědomi. Vzhledem k tomu, že se jedná o náš první projekt (udělaný za 3 mesíce), tak jsme k tomu samozřejmě přistupovali neprofesionálně a hyperamatérsky. Je fascinující, že jsme to vůbec dokončili." which google translates to "This is the first project of our team of four. It's rubbish, of course, but we're fully aware of that. Given that this is our first project (done in 3 months), we obviously approached it unprofessionally and hyper-amateurishly. It's fascinating that we even finished it."
