I know. I'm like completely OCD, though. I tried going back to the regular pack for the screeshots, but they were asymmetrical and it really bothered me. Also, I just burned half the inside down on accident.
[lol] Now, the lava is actually glowstone, and the rest is being restored.
On a side note, before I burned down my own arena, I tested out how to build a daylight sensor, which actually works. There is a thread for it on Minecraftforum.net, and now you can always know whether it's day or night while you're in the mines. Grass can only grow in the day, and it dies at night if it is not properly lit. In turn, this machine senses the growth cycle of grass, and switches an RS NOR latch when it is daytime. Check it out:
