I am trying to amass some EPS drawings of twinned crystals for an exhibit, and I am having trouble finding or making (SHAPE) examples other than of feldspar.  Does anyone have a vector drawing of, say, polysynthetically twinned calcite that they would share with me.  I have had to customize drawings of fluorite and pyritohedron penetration twins if you want to trade.
