Jim Sorenson has updated his blog with another design sheet that did not make it into the The Ark Addendum. This time it is for a background model of the Quantum Compound.
"In honor of Iván's nifty Day of the Machines movie poster, I bring you The Ark Addendum: Day of the Machines. It features some of the background models from that episode. The Quantum Compound, home to Quantum Laboratories, is where TORQ III resides. It's defenses proved woefully inadequate against Megatron. Once Megatron overwrote TORQ III 's personality with his own, he was able to use it to take command of machines remotely. Given the Decepticon's omnipresent need for energon, he took control of many oil tankers and directed them to a Cybertronian oil base."
