Ubisoft's 2008 holiday card is complicated, but cool.
Upon arrival it looks like what you see at left. The card has pieces that you can punch out and assemble to make figures from the Rayman: Raving Rabbids series.
It seems that there are four different possibilities. GP's card included the black rabbid pictured here, which was assembled by a team of experts at GP HQ.
The nice thing is that you're left with a toy that will last the whole year through.
Like the Jelly-of-the-Month Club, it's the gift that keeps on giving...
UPDATE: Ubi, full of good cheer, also has an animated holiday card.
