Lately I've been putting my paintings on MOO Card and liked the results - but I wondered what happens once everyone starts having a MOO Card - what's the next step?
Looks like this could be the next thing in business or personal cards, according to Boing Boing:

"..The card is for a landscape architecture firm. On the card is a printed plan of a landscape design of a miniature garden. Seeds are embedded within the card so in just a couple of days the seeds will sprout through the holes of the print. "
If some of the architects I work had cards like this, for some of their more popular plans - I think they'd be very successful with it.
BTW, I'm still in Aix till Thursday - not able to post as much. I put up some interesting footage on Paul Cezanne's studio that I visited yesterday - A visit to Paul Cezanne’s Studio in Aix.
