A clever cosplayer was able to simulate the anime casting spell effect using a modded Nerf blaster and a spinning LED wand.
The result is anime styled casting glyph that's 3d and can be seen in any angle.
Here is another cosplayer - doing a dr. strange effect in real world!!! Amazing!!
The technology is amazing because it's also what could be used for that blade runner style of holograms coming soon to a city near you.
You can create this kind of effect with free software like black magic designs free fusion compositing software.
Its film level effects for free. I use it myself for visual effects that i do.
and if that's not enough - check out this holographic drone using the same led style
Led holographic displays are becoming more pervasive - and that Blade runneresque future is already here.
If you thought this was neat - please upvote =)
