Knockout and Reveal are two programs that involve playing with pictures in ways that are intended to encourage and stimulate various aspects of visual development and prediction. Produced with a focus towards children, but could be useful for adults too. Activities can be set in one of the many styles available, including loading your own pictures to use. Any configuration can then be saved to disc. Knockout lets the user change areas of an image - such as the colour of windows and the door in a house, or colours in patterns.
Some options enable users to receive a sound reward on completion of a task.
Reveal allows you to uncover areas of an image in steps, including a 'snaking' option that only permits a limited area of the image to be on view at any one time. Both programs allow you to include your own pictures. All products sold subject to availability. Prices and specifications correct at time of writing.
