So, my knitting/spinning friend Joanne has an extremely talented BF, Drew. Drew makes things for a patent firm--they'll make the product you dreamed up, figuring out the specs required by the patent office, etc. So he has Access to Tools.
Which you would need to be able to make something this cool:
Yes. That is a piggy bank.
The slot is in it's back. The money is extracted by spinning the (personalized) nose up, revealing a smile. And it has the cutest little corkscrew tail.
Is that not the most adorable thing?
As you can see, it's about 6 inches tall. I think there's another size that can be gotten too. This one cost $40, which I thought was very reasonable for something (a) personalized (b) numbered by the artist (c) unique and (d) that will last my DS a lifetime.
If you want one, you can contact meepmeep981[at]hotmail[dot]com and place an order.
