Scrollit 2X vs ParaGraph3D

ScrollIt 2X turns your iPhone or iPod Touch into an L.E.D. double message display board. ScrollIt 2X will help you tell your friends, colleagues, or anyone something - when they can’t hear you: at a club, concert, class, meeting, lecture, or even a restaurant. Just type your messages and hit Display, and ScrollIt 2X will scroll the messages for everyone around to see. What adds to the fun is that ScrollIt 2X offers easy-to-type emoticons right from the same keyboard. Make your text even more fun to watch! The phone vibrates quietly to let you know when the message has finished. (Replaced with a short beep on iPod Touch and iPad.) The endless-loop option lets ScrollIt repeat your message indefinitely.
