The Chiropractors’ Association of Australia has developed the Sit
Right Widget as a simple tool to prompt computer users to take more
regular breaks. The default setting is to prompt for a break every hour,
although users can change these settings for 20 minute or 40 minute
intervals should this assist with meeting advice from your healthcare
professional.
It is free to download, and is available for Windows (Windows XP, Windows Vista and Windows 7) and Mac OS X (Lion/10.7.x only).
