Hello all
I am looking for some form of JavaScript or other function that will replicate the old style computer screen letter loading.(Loads one letter at a time) This is for a nostalgic effect of an old computer effect...
It hard to explain I guess because I am not sure that it called a ticker or marquee but what I am looking for is something that will allow a page to load letters like the old war games movie computer screen( one letter at a time but fairly quickly). Not a scrolling effect..
Anyone have any ideas.

Thanks
