Prodder

It sets a periodic, unobtrusive notification to prod the user to check their posture whilst they are sitting in front of their computer. The notification disappears after 2 seconds, so it will not interfere with anything else on the screen. The default is every 10 minutes, but users can change the interval for prod and also change the message of the notification, if they prefer to be prodded about something else, like stretch their legs, drink water or take a break. The Prodder can be easily turn off and on from the toolbar.
