Ti è andata ancora bene, su eBay una volta ho comprato un set "con scatola originale in buone condizioni". E come l'ha spedita? Ha attaccato le etichette postali direttamente sulla scatola :-O Meno male che a me interessava il set e non la (...) (19 years ago, 11-Apr-07, to lugnet.org.it.itlug)

(...) Som further clarification... I was back in the 3x3 matrix world when I wrote this: the true inverse of a rotation + translate in psuedo-4x4 notation is as follow [ R11 R12 R13 x R21 R22 R23 y R31 R32 R33 z 0 0 0 1 ] goes to [ R11 R21 R31 xp (...) (19 years ago, 11-Apr-07, to lugnet.cad)

Ciao volevo segnalarvi un mio acquisto sfortunato, affinchè non possa capitare anche a voi. Ho acquistato a caro prezzo 3 10039 da Planet Lego di W-largo alias Petit Stephane. Lui mi ha avvolto le scatole in un foglio e me le ha spedite. Come ovvio (...) (19 years ago, 11-Apr-07, to lugnet.org.it.itlug)

What was the purpose of the LEGO colour change? Well, I think the whole thing was not initiated by TLC. I remember that not only LEGO parts changed their colours - there were some grey shade changes overall: some medicine packaging tubes, ceiling (...) (19 years ago, 11-Apr-07, to lugnet.color, FTX)

(...) Sono d'accordo!!! Accetto i nuovi colori, ma non accetto le differenze cromatiche sullo stesso colore! Posso capirlo se il set è per un bambino che lo monta, ci gioca e basta!

(...) snip (...) What a neat little tractor! I especially like the exhaust pipe and the bumper - very creative uses of those parts. I really enjoy seeing so much detail in such a small MOC. Great work! Roy (19 years ago, 11-Apr-07, to lugnet.town, FTX)

Now, with the NXT set, the "white" parts are not white, (...) (19 years ago, 11-Apr-07, to lugnet.robotics.nxt)
