Actually this little game has been fun. Might even have to pay for the registered version -
If you haven't tried it - you really should. Some thought and a lot of trial and error - but I found it all pretty relaxing (when not cussing - LOL)
Made it through all the stages - here is the last contraption:
U-Turn
If you are looking at these - use the blue + and - buttons to zoom out to see the whole scene.
