What Is This ?

Bernie & I saw this today.
At first we thought, "what the heck is this"?
Then we realised what it was.
We had not seen one like this before.
What is it ? I know a lot of you will know :)

I'd at least need a hint...like where were you when you saw this? My imagination is going wild but don't think my 1st guesses would be even close.

a stand to hold a musical instrument

Hmm, I have no idea! Very odd looking, whatever it is!

[Rick Schies]

Is it a computer mount or a TV mount?

@hwy61 @sarasdadandmom @melissapike - it sure is a funny looking thing.

@digitalrn - You guessed correctly. I forgot to take a photo of one with a computer attached. It was the oddist looking this thing I had seen in a long time.

Wild! It looks like it should be in a technology museum.
