I use OnePager Pro by Chronicle Graphics. It produces a one page graphical (Powerpoint) summary view of your project. The summary lines are laid along a time scale. You choose which lines/groups to show (I typically choose major summary groupings like Engineering, Procurement, Installation). You can change the color of the output, the size of the lines and the titles. Easy to use, inexpensive and my executives like the colorful display. You can show more than 1 project, but the font sizes have to be smaller and smaller the more you include.
