Madagascar Lace plant varieties?

[HybridHerp]

Whenever I look up this plant, I keep seeing mention that there are different types and varieties of this plant. Things with different colored leafs or differences in the windows in the leafs and the ultimate size of the plant.

I was wondering if anyone here knew of the different varieties, or at least knew what the most common of these plants are like. Feel free to post pics of your Lace Plants, if anything maybe we can formulate some kind of guide as to the differences between Lace Plant types.

On a side note, I'm now wondering how it is that apongetons aren't more like swords in that there are a TON of variations? Apongetons just seem to only have variations between species....but could you imagine if we got, say, a lace plant that was red in color through selective cultivation? Can we somehow make that happen one day? :P
