Marq iPhone / iPod Touch application scrolls messages, marquee-style across your device for others to view from fifteen, twenty-five, or more feet away. You can save your favorite messages and options or just bookmark Marq and create new messages anytime inspiration strikes.

A few of the unlimited uses for Marq:

• Display your name, phone number, e-mail address, or web site.
• Communicate with someone across the room or across a table in a meeting.
• Silently let a speaker know his time is up.
• Root for your favorite sports team.
• Tell a joke.
• Flirt

There is a special local version of Marq especially for iPod touch users that works without an internet connection. When you are connected, go to http://www.rjen.com/marqx.html click on the link on that page and then bookmark the resulting data url. You can then use your newly created bookmark anytime, anywhere.
