About the Commtap Symboliser for PowerPoint
The Commtap Symboliser for PowerPoint is an "add-in" for PowerPoint which enables you to quickly add pictures and symbols to text. Type some text (for example "car"), click a button, and an image will appear, click the button again, and if there is an alternative image for "car", that will be displayed instead.
You can use the small built in symbol set that comes with the symboliser (Mulberry), you can download free picture symbols (such as the large Arasaac picture symbol set http://www.arasaac.org/descargas.php - scroll down to the English symbols), you can purchase symbol sets, or you can make your own (for example a set of people's photos).
Also included with the symboliser is the Commtap Grid Maker for PowerPoint - this allows you to make grids much more quickly than with the standard PowerPoint controls.
