Wall display is a giant monitor for collaborators

An $11,825, 60-inch electronic Wall Display from 3M Co. can plug into a notebook or desktop PC and act as a giant monitor on which users can create or edit documents, presentations and spreadsheets.

A user writes directly on the glass with colored dry-erase markers or taps the screen with a blank marker to pull down menus and select items.

Remote users chosen from a Microsoft NetMeeting address list can chat and collaborate in real time. The screens can be printed out in color and sorted, saved and distributed in normal Microsoft Windows fashion.

The 4-inch-thick, digital-light-processing display has the same landscape orientation as a notebook LCD and requires no adjustments'there is only one on-off button.

The 85-pound unit can roll or hang on a wall, and it operates via a top-mounted projection arm with a replaceable, 2,000-hour bulb.
