the URL worked for me. if he is trying to run 10 meters worth of LED's, each spaced 2cm apart that's over 5000 LED's, that is either a lot of 4017 ic's (if he's trying to get them to
all be sequential) or he may need to drive a considerable transistor if he only wants to sequence 10 (which is still 500 LED's on at a time). he can try an LED sequencing circuit combined with multiple driving output. like this circuit (thanks to audioguru for finding it):
4017 sequence
