random.seed(time) sets the seed to the same value each time. (You are 
passing a module object, whose ID becomes the seed). Try 
random.seed(time.time()). Also you can set the seed once, then let each 
call to uniform get the next "random" number.

Also consider:

mypiece = []
for piececount in range(8):
   mypiece.append(LinePuzzlePiece())
   mypiece[piececount].printcolor()
