Mote - Hi and thanks!
Yes, this is a semi-long-term project. I've been playing with the layout and designs in a creative world. Still haven't figured out exactly what blocks I'll end up using, but I'll still collect anything from the list above... went and mined a bunch more diamonds, so they're my preferred currency.
I've never been in a mesa biome.. didn't know until now that you can find the stained clay there.. huh, learn something every day.
