Windows metafiles are used and Build It enables them to be 'broken down' into stages that are built every time that a child presses a switch. Tools are provided to enable carers to build their own activities. This has enabled a wide range of picture building activities to be produced. This package enables children to interact with pictures in a number of ways. Knockout lets the user change areas of an image - such as the colour of the windows and the door in a house, or to colour 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. It includes a snaking option that only permits a limited area of the picture to be displayed. This is an early painting program for the young and developmentally young. The size and colours in the palette can be set for a particular activity as can other options such as whether to allow painting, filling, picture stamps, symmetry and up to four picture 'stamps'. The feedback regarding the current software has been most positive to date.
