1 Obi-Wan: It’s over Anakin! I have the high ground!
2 Anakin: Oh. Yeah. I suppose you’re right. The high ground is an insurmountable tactical advantage.
3 Anakin: I guess no force in the history of the Galaxy has ever prevailed from a slightly lower elevation than the defending units.
4 Anakin: I mean, you have a good half a metre on me here...
4 Obi-Wan: Okay fine! Just attack already!

Last time I made lightsabres in the comic, I had forgotten how I made the glowy effect in the past, and I figured it all out again from scratch. And I wrote down how I did it, so I could replicate it more easily in the future.

Wind forward to this time, where I'd forgotten how I did the glowy effect last time - and I'd forgotten that last time I wrote down how I did it. So I figured it out from scratch again.

And then only after I'd finished this strip did I remember that last time I'd written the method down. And so I compared it to the method I'd just come up with, and of course it was completely different.

So now I have two different methods for making glowy lightsabres in Photoshop.
