Post your effects!

I know everyone here has experiments and such that they've made that don't necessarily warrant their own thread, so... now there's a thread!

Let's see some cool/interesting/weird effects you've made. Never finished them? Well, now's the time! Polish them up, make them look good, and post them here.

Screenshots too, please

I'll start:

It's a swarm of glowing... uh, things. Click and hold to collect the swarm, release to make it blow up

Shows what you can do with just a simple gradient, along with a snow effect.

A little bling made in .99

That bling effect is nice and subtle, I like it

Here's another (for v0.98.9):

It uses Additive on the particles and Overlay on the layer, which gives it those weird, smoky edges.

Note that this one won't look the same in 0.99 because it uses the old Overlay, which has been changed. (So don't toss out your old Overlay shader when you do the final switch to .99... save it and rename it something else. Even though it's not a proper, true-to-life Overlay, it can still do some cool stuff.)
