Two more realistic portrayals are in the center of http://danbooru.donmai.us/posts/2085580?tags=fav%3Aonlyaw+mecha
The tag is lens_flare.
Please ask these kinds of questions in topic #12251.
Those are actually diffraction spikes. Diffraction spikes manifest as multiple spikes radiating from a point of light while lens flares manifest as overall haziness and artifacts in the image. There's no tag for diffraction spikes.

Ah damn ... you are right. ;D
I was thinking about the lens flare lines created by anamorphic cinema lenses.
The starburst (diffraction) effect in the second image certainly looks like it was caused by a lens with 4 blade aperture.

Should diffraction spikes or starburst diffraction become a new tag?
Yes!
Examples of lens flares and diffraction spikes:
Bonus: Some examples of anamorphic lens flares: post #2378642, post #2383337, post #2393349, post #2336076 (real world examples: 1, 2, 3)
So which of these (if any) are diffraction spikes?

post #2424195
post #2418715 (from the sun)
post #2418748 (from various water droplets)
post #2305757 (from the ring)
?
So I know what I'm looking for in the future.

post #2439268: Doesn't look like diffraction spikes because there is no light source. However, the picture should get the bokeh (out of focus points of light) tag.
post #2424195: diffraction spikes + sparkle
post #2418715: badly visible diffraction spikes + veiling flare (type of lens flare) without the artifacts of ghosting flare (in this case)
post #2418748: diffraction spikes + sparkle

Don't forget to create a wiki entry for any new tags (especially since these are things people without a photography background are probably not familiar with) and add them to tag group:image composition.
would many gurren_lagann style_parody qualify for this? think that pool #758 might need a rewrite to mention this new tag.

I believe so... seems like a lot of work though.
