The last time I saw this guy was in 2009, when he was still on temporary display (and I was just a tourist). Back then he moved and emitted smoke.
I finally got a chance to go to Odaiba again (finally, after living here for one year!), where he is now a permanent part of the landscape! Unfortunately, no more moving and light and smoke effects :< Still, it's nice that you can just come and see him anytime now
