Many people with Scotopic Sensitivity will find this application useful. This is where we would like to introduce T-Bar to you.
T-Bar is a coloured bar which you can either drag around the screen or lock to your mouse. It can have ruled lines or not, depending on your preference. The colour can be chosen from pre-defined options, then tweaked by altering the red, green or blue sliders to get the perfect colour, the transparency level can be adjusted, again to suit the individual. All the settings are saved between sessions, so there is no need to readjust the next time you use it.
