I finally found a tool that i have been trying to find for months. It is a "simulator" for Braillers. This program is a very simple, straightforward application that will happily run under Windows Xp and Vista. It is called Perky Duck.

The company that provides it is called Duxbury Systems and the direct link to the application is Perky Duck Link Please note that i have included this link to help out. It may change in the future so please go via the main link to Duxbury Systems and then choose products. Look for Perky Duck

I have installed and used this on my laptop and my desktop now and it is brilliant. This program should be encouraged to be used by all people learning Braille.
