Random Fillable Shapes

[DiscoverIT]

I work with people who have physical disabilities and one user drew 351 indiscriminate lines in the hope that he could eventually drop a variety of colours into these random shapes to create a mosaic of colours.

I had to explain to him that the way he worked would not produce any shapes that could be filled in .

Does anybody know of a way of producing random shapes in Xara that could then be filled in merely by dropping colours on it? Or is there a dedicated software program that can achieve what I am looking for on his behalf?

Thank you, DiscoverIT
