Interlock - Jigsaw Puzzle Program

The Interlock program creates jigsaws from any picture files in .bmp, .gif, .wmf or .jpg formats. Intended originally for children the number of pieces can be varied from 4 (for the youngest child) to 100 (any more would be difficult on a normal computer monitor). In addition to photographic images pictures can be also drawn in Paint or another drawing package and then turned instantly into a personalized jigsaw.

Interlock is available (for free) as a downloaded zip file for Microsoft Windows 98/XP etc. Download Interlock
