Looking for ways to add an interactive element to your next event? Hamburg, Germany-based Zelfmade has introduced a mobile-to-screen tool that allows guests to transfer images and messages from cell phones onto an LED wall during an event. Guests send their messages via text messaging or multimedia messaging to a number displayed on the screen, where the messages are collected and edited online, then sent onto the wall for event attendees to view. Motorola used the high-tech service during MTV's 2005 Campus Invasion events in Germany. For more information, call +49 40 386 29 000 or visit www.zelfmade.com.
