One of the so-called benefits of a capitalist competitive society is the avalanche of useless, silly, and expensive gadgets. They all have a negative effect on the energy and pollution in a world that is burdened with a need for utility and economy. This is acceptable as a one time joke along with the hand buzzer and the fart pillow but more than once requires a cream pie in the face. Also, it seems to be in production and qualifies as spam.

Yep, it's spam.

I think there is nothing wrong with a little good-natured fun. Cheering up is what people need. It's completly manual and there-fore enviromentaly friendly. There is a lightbulb hat in production, but of this sort. Please reread my description. Thank you, I appreciate hearing people's point of view. It will help me improve inventions or decide whether they are practical enough to sell. I am curious to know how this qualifies as spam.

Also the hat in production is felt and the lightbulb cannot be raised and lowered for specific moments. I made the name up and created the ad for posting purposes only. (Meanign there is no LightBulb*Hat, nor any hat like it being sold this way.)

There fore the hat (correction) does NOT have anything like it on the market.

I am not an enemy of humor but a joke has as one of its key elements a quality of surprise and novelty. The apparatus you describe, no doubt, has that quality for the first exposure at a gathering and might evoke a chuckle or two but repetition of the light to indicate a great thought more than a couple of times characterizes the user pretty much as an immature idiot and is rather embarrassing for all concerned. I suppose it might have some adherents for 10 year olds but unlikely for even marginally sophisticated people.
