To be clear, what I was saying was:

- It would be really cool if we could show a finger print on screen when 
the user scans their finger
- The fingerprint wouldn't have to be the user's fingerprint, just as 
long as it looked like a fingerprint and looked different than other 
people's fingerprints

I don't know what fingerprint scanners store (actual image data, or just 
enough information to identify the print or what).  Even if we don't 
have a full image to show, we could potentially just perturb a fake 
fingerprint seeded by whatever data we do have.

Having said that, I think some scanners do give image data.  David 
pointed me to this post he made a long time ago:
