The below code is not required. I just wanted to clear up a bit of confusion from questions I've received. You can create private/public keys from any source you want and create any design you want to go under the holograms. The below is just some code that can help with this process if you want to use it.
This code is a combination of python and php scripts. I have included instructions and a shell script to get it up and going on Ubuntu as that's what I use for this.
The code is hosted at
https://github.com/jondale/serpcoinYou can download a zip of the scripts directly
here .
I hope to put up a few template images here soon so if you are not comfortable using these scripts then you could use those to just add the information you want.
I used the script to create 25 labels and below is the result:

Front side of the page.

Back side of the page.

Cut out the label and folded it.
This is the inside.

And the outside.

Attached to rolled up painter's tape.

Aligned and attached to the sticky side of the hologram.

I highly recommend using painter's tape (thanks casascius for this tip) to align and attach labels. The cheap brown kind is the best because it barely sticks which is what you want. It makes aligning and being precise so much easier than any other way I've tried. With the honeycomb release, messing up can ruin a hologram and nobody wants that.
