Those are really cool. My wife wants me to make some decorative panels for the house now. I've seen designs that look like water ripples with very natural wave patterns that would look really cool tool. Would be much harder to design though.

Just depends on the software and amount of detail your looking for. Another consideration is weather you need to "panel" the tiles so the the edges are continuous. Which takes a little more time. But like anything, the more you do it the easier it becomes.
