I was feeling crappy this morning, so I just zoned out with Minecraft.
I built a simple mine cart system to get up and down from my mine. Much better than walking that long flight of stairs.
Then I dug some stairs just for the heck of it,
and found redstone and diamond right outside my mine's basecamp.
When I'd dug to the surface, I boated around for a bit. My tower is visible from a long ways off, and it's not even up in the clouds.
That inspired me to explore a nearby cave. I discovered it fairly early on, but it was a big vertical shaft going down pretty deep. So I put a sign up "Deep Dark Cave" and left it. That sign was
very accurate. I didn't even come close to exploring it all. I didn't see bedrock, but there were quite a few very large lava pools. I got horribly lost and it took me quite a while to get out, but by the time I did I had: 6 Diamond, 22 Redstone, 10 Gold, 43 Iron, 8 Brown Mushrooms, 5 Red Mushrooms and a bunch of coal (some of which I'd had to turn into torches).
Then I finished up my rooftop garden:
It's really peacful up there, I'm so happy with how it turned out.
At night, looking the other way.

And the view from the top is spectacular.
