For Christmas I received a MIB copy of 8485,the Technic Control Center II, and have 
built the Tyrannosaurus Rex, the second alternate model; here are pictures of it being built.  
Warning: it contains the odd blurry shot as well as some really sloppy stop-motion sequences.  
But it's not Art for Art's Sake, just a record of my experience building it.  It was a real 
challenge for me, a usually non-Technic person, and I'm delighted with a Technic set that 
for once doesn't build a vehicle - as flashy as they may be, simulation of something alive 
is a whole different ballgame and TLC has excelled in this design.  I'm really delighted 
with this set, and hope you find this photo collection enlightening if you're not already 
familiar with the model.  Here are some facts and figures:

Pieces in entire set: 1063
Pieces used: about 90% (the last pic shows pieces left over, I didn't count 
them)
Motors: 3
Flex cables: 6
4x2x4 Gearboxes:2
Worm gears:3
Batteries in control box: 6 'C's

Size, including control box: 10" wide x 14" high x 22" long
Scale: about 1 inch = 2 feet, or 2-3x minifig scale

Motion:
Tilts head up and tail down, and vice versa upon reversal of motor
Swings head and tail back and forth (continuous loop)
Moves head forward and back while opening and closing jaws, while moving claws 
back and forth (continuous loop)

Time to build: ~7 hours over a 24-hour period, with constant interruption
Number of pics originally taken: >110
Camera batteries used up: 4 sets of 4 AA's

Mistakes made: at least 8
Mistakes that required disassembly: 1 (forgot to put rubber band around motor 
shaft under tail, see pic 20!)
Pieces dropped on floor: 2
Pieces lost: 0, thankfully
Sore fingers: 10
Sore back: 1
Tired eyes: 2
Fun, challenge, and education about Technic techniques: Immeasurable
