From the submitter:
A do it yourself computer tower fan. The fan and Power Supply went out on our computer tower so my husband came up with this..and it works.
The submitter said it's used to help cool the laptop, but I have a feeling that this is doubles as a homemade privacy screen. ~Not-So-Handy Andy
It'll last for 10 years... or until it rains next. Whichever comes first.
