I have quite the backlog of mosaics to cover. I guess it's best to start out small, just getting one of them posted. And in this case, when I say start out "small", I really mean "ginormous". There was a LEGO convention in Manchester this past weekend (officially endorsed by The LEGO Group), and this giant mosaic was on display.
Jack R. (The Expendable), who took the picture, had to "panorama-ize" it to get it all in one shot. I get the feeling that it would be even more impressive in person.
Thanks to Bruce for the tip.
