I remember the acid house generator, but I missed that constellation of samples sounds really interesting. Would love to see it if you had a link.
var y = (0)["constructor"]["constructor"];
y == Function; // true
Then he basically does this ($.$ == Function): Function(
Function(
"return \"alert('I love you');\""
)()
)();
The inner function just returns the string "alert('I love you');", which then becomes the body for the outer function.
