Thank you for the advice everyone :)

I was trying to make an animation showing wallpaper group transformations.
I just couldn't figure out a good way to organize the graphics. Mainly I
was having a hard time figuring out how to group objects together so they
undergo transformations together (as one can do in animation software for
example), but still have transformations possible within those groups of
graphics. I know mathematica isn't an animation oriented program, so maybe
the problem is I was trying to do something with it that it isn't made for?
