You can achieve those effects easily with javascript frameworks such as mootools or jquery.
I’m not aware of any snippets IIRC. (MG can do some of these). Anyway, here’s the links to mootools and jquery official homes. There’s so much you can do with these babies....(I prefer jquery, of cours
). You can also google mootools and jquery to see what other people have done with them. Btw, there’s other jsframeworks out there, just google.
