I'm getting there ;-)
This is pretty difficult stuff. I'm trying to make them really great before I release them.
I can tell you already that the cumulonimbus will be easy to use "as is", but not be exactly easy to modify. Just a few tweaks here and there and you may ruin the looks. I'll also have to write up instructions on how to use the nodes in the network, which parameters better not to touch etc.
I'm hoping I can release it later on sunday, but don't take my word for it.
Cheers,
Frank
