Thankful
Thankful or "Hello" is a screamer site hosted on Neocities.
When you go to the page "hello" you see a notice telling you that the site requires autoplay to work correctly, this is a lie, it is actually used to make sure the screamer audio gets played correctly. When you proceed after turning on audio you are then taken to another page (thankful) where you are met with a screamer of an edited face inverting in color rapidly.
