Well I found this out when it was getting dark and I was thinking of pistons so hey why not make a piston house even though that doesn't make sense. Anyway before I went to sleep I noticed the light levels where the same even though it was all blocked up and when i woke up, the light levels changed to day. I don't know if this was intentional but I guess they really wouldn't have expected for someone to make a house out of pistons I've taken the liberty of taking a few screenshots for you guys, tell me what you think!
Give a man a fish, and he'll be fed for a day.
A double resolution graphics pack that stays faithful to the originals.
edit: i cant reproduce it. hmm in fact pistons are transparent as far as i can tell.
not to be rude but transparent means to be able to see through like glass...unless im a fail at english too...
