Seems like this one is generating lots of excitement! Few ideas that came out of the youtube tutorial (http://www.youtube.com/watch?v=T39c5NPSy0E&feature=gp-n-y):

• allow a facade to have up to 4 states (recipe, you add a 2-phases facade on the left side of the integration table, one simple one on the right, and one extra pipe wire for activating the new phase. There needs to be some kind of priority algorithm in case more than 1 wire is active at a time).
• implement a transparent state.

Argh, @SpaceToad, merge 6.0.x into 6.1.x first, please.

Done!

So (1) is done!

How about (2), implement a transparent state?

First I should understand this feature.
Transparent state - facades and pipes should be invisible?

Just facades I'd say.

So facades should fully visual disappear by external trigger (wire signal), right?

Can I take this? :)

Sure thing!

That's the idea.
