When I was in university, I did something similar in Python. I printed it off in color and brought it to a career fair. One guy loved it excitedly. But I didn't hear back from him :(. And that's the story of how I cam to work in Java ;)
This is why when you meet someone at a networking event:
0) Have brought a pen or cell phone.
1) Always get their business card or contact info.
2) When you get someone's business card, always write down where you met them and what you want to ask or show them. Otherwise, you end up with a pile of cards and no memory of who they were from.
2.1) If you actually had them type their email into your phone, sketch out the email, but don't send it.
