I've heard about some fans fearing that GBC movement may slow down, as some are leaving this area and number of modules displayed in events may decrease. One reason may be the high level of babysitting these modules require to keep them working in the events and the wear they induce on some parts that are heavily stressed in the modules moving parts.
So and because I'm an unconditional fan of GBC displays, I've decided to include here today, two videos from Alban, featuring the last and large GBC display at last Fana'briques event (27-28 June 2009).
GBC is clearly a big public attraction and inspirational to kids and adults. But it only works as a collaborative effort.
Likely just a local US phenomenon and not yet an European concern. Anyway just my two cents, to keep the interest alive.
Next round at BrickFair near Washington DC, end of August.
