ScrollIt is a unique application that turns your iPhone or iPod Touch into an LED message display board. It is an ideal app when you want to convey a message to your friends, colleagues, or anyone in a crowded place where they can't hear you, like a club, concert, class, meeting, lecture, or even a restaurant. With ScrollIt, you can easily type your message and hit the display button, and it will scroll the message large enough for everyone around to see.

What's more, ScrollIt offers easy-to-type emoticons right from the same keyboard, making your text even more fun to watch. The phone vibrates quietly to let you know when the message has finished, and the endless-loop option lets ScrollIt repeat your message indefinitely. It also has a simple yet powerful design with no confusing buttons or switches, mini-live preview, and three LED shapes: neon, round, and square.

Overall, ScrollIt is an excellent app that offers unlimited message length, right-to-left display for Arabic or Hebrew, and a recently-used message list with one-tap access. If you want an app for scrolling texts, this is the one you want.
