On the way to shelving

It is so rare that I see something interesting on all the internet computers people are living at in the library. And while it would be super nice to see someone reading my blog, or manipulating massively complicated screens of pure code, what I reliably see is people playing addictive and simple games involving colored balls, email accounts full of spam, TV shows, bureaucratic looking forms, and shopping, shopping and shopping. So it was with great pleasure that I walked by the upstairs internet computers just now and saw a screen full of strange, multicolored, whirring spheres.  It wasn't a game. It was too good for that. It was maybe astrophysics? Biology? Something surely in the sciences, but maybe the mad sciences? I can't entirely discount that it was some sort of alien communicating device. All the aliens I imagine are big library users, or employees, or whatever.  But it could have been some homeless person working something out that will win them a Nobel Prize in 3 years. I don't know. I didn't ask. It's a library. I just mind my own business.
