I made this growth cell to demonstrate the growth property of quartz that was added in the beta. It is 27 pixels(6 pixels high, 5 pixels wide) and can grow absolutely massive crystals. Like I said in the save, you can use this without credit(after all, it's just a LN2 cooler and a BTRY). This has many uses such as reactive armour(like SHLD armour, but transfers heat), timed walls, and much more. Any suggestions on how to improve will be greatly appreciated.

Damn straight >:D
And thanks for the feedback guys :D

So long as the crystal keeps growing only the center will get that cold. Of course you could build a shutdown mechanism(either timer or event based). I must say I do like quartz, we need more complex elements with numerous special properties, their interesting and useful.
