As I sit in front of my computer this morning, I'm suddenly aware of a steady, constant, purring sound. That disturbance is my computer dilligently stuffing sound into empty spaces around it's workspace.
That's about all I know about computers.
The question arises, "Are there empty spaces around my workspace that are waiting for my Purr?"

Meanwhile, I'll just keep coaxing my treadmill powered scooter uphill!
