Those effects are something that are supposed to be used as window animations, such as furnaces, reactor's inspection windows, mad scientist's computer monitors, magic mirrors, amniotic fluid in a cloning facility... or in transition screen... Well, they are abstract.

Of course they could get resized or cropped, to meet any need.
Several panel can be obtained from the same sequence or more sequences can be combined to create a complex system, not to mention that blender users can use them as material for any light source or energy field.

"TunnelPulse" isn't supposed to be a seamless animation, but i'll see to add the corresponding seamless animation.

The .gif files contain several sequences, each with a particular effect. The name might suggest what's going to happen. I deemed unnecessary to put all the files in the previews.

The 2 zip files contain the original rendered frames, first one the planar effects, the second one the tubular effects, they are nominally 32 bits png, altough the alpha channel is unused.
