Bukkit

You are probably wondering... Why should I get this plugin instead of just making my own pretty text? Well, here's a few reasons... There's about 5 minutes of your hard work. Also, you screwed up all the e's. They're too short. Try again.

Here's about 40 seconds and a few height measurements. Pretty, isn't it? (Build 9 blocks up to perfectly space lines of text)

Screwed up? No problem. That's what the /undoprint command is for. /undoprint restores all changed blocks, including block data, and it even memorizes an amount of prints, customizable in the config.
