We just received 2 of the 3 winning objects from Sculpteo: the V8 engine desktoy and the "Weather Merry go round". Object #1 should come soon as well! The winners will thus receive their gifts very soon :-) Congratulations to them again!
Nota: the mechanisms seem to need a bit of "oil" (~removing the dust between moving parts mainly), but it seems they will work OK with some care from the happy winners.
