I feel stupid for posting this but... How do you make it so on a sign it starts putting lots of little %$^gf$%^5_+-_)+)&*( things and they never stop moving. If you know how or where it tells you how to do it please tell me.
Oh. There's a guy on SMP7 called Gremlindan, his first res shows all the sign codes and colours - you should check his res!
