Ehm, could anyone tell me what happened on the server?
Theres a massive ammount of gravel in the middle of the staircase, and there are some stone blocks obstructing the corridor on the 10th floor or so.
On those stone blocks are buttons, which trigger pistons below.

May I ask, who built that, and why? I don't really see how it fits with the Tower :S

Also I noticed the massive "we're alive" sign made out of glowstone - I personally think it's over the top, but I can live with that.
The gravel/piston thing just confuses me though.
