I would like to see some different covers available other than the C9. I love the flexibility the nodes add to my display, but I also want something a little more traditional looking. A choice of covers also allows one to add some depth and character to your display. C9 on the roof, C7 in the trees and strawberry on the shrubs. I would likely use C7 and the round strawberry covers if I found some that would fit over the SS nodes.
I also think a net style light would be great for shrubs. In object oriented programming software, this would make sweeping fades easy to do.
