Black hole or whirl

As a photographer or photography lover, you see an image, object or scenery and admire on it. It could be turn as photo. This is happen to those who hold a camera or at least a smart phone. Some others try little further to create unusual photos. Some of them take risk and do adventure to make an amazing outcome. Others try some techniques such as light painting, micro level photography, panning, zoom burst, HDR, etc.

I tried a different method. It was not adventure, very technique or costly. The result is given below as an image.

An object could be black hole?

I took this image and asked friend to tell what it is. Some said it looks like black hole or some kind of whirl. Some others said it looks like UFO (Unidentified Flying Object) / flying sauce. Actually, it is an USB powered mini fan with blue LED. It uses for laptop to reduce heat. I kept it in a place where I can get enough light to control background as black. I did several clicks with different angle.
