Gel...From Scratch!
I have no comment I am dumbfounded at how awesome this is
HOW you do that
Thanks! 
It's mostly clever (ab)use of Particle System operators. For example, I used Velocity Repulse from World with a negative value and Collision Via Traces to make the blobs stick to the ground.
Maybe you can help me a little with it I would love to have those kind of textures for my paint gun
Unfortunately I've had to change my approach a little bit. The gel on the ground looks awesome this way (as well as on walls and ceilings and the like), but it's REALLY expensive. If you have more than 16 or so splatters on the screen at once the game crashes (apparently the Blobulator doesn't understand when the simulation is frozen).
If you look at my Ice Gel in the Hammer Notepad thread, that's my newest attempt at making a cheap ground particle.
I don't really like the texture of your Icey and gravitation Gel. It looks too less Gel-Like for my taste 
But if ypou don't get it otherwhise, without game-chrashes, there is no other optio, I think
But Can't you try to make it look similar to info paint sprayer Gels?
And whats now with the cleansinggel? since they dont affect each other., you woukd need to make an own cleansing Gel for your Gels, right?
Yes. The Cleansing Gel for mine also clears away normal gels, since it's just a standard blob of water with a script stuck on it. But the others aren't normal gel blobs, so they don't clear anything away.
Just an idea - couldn't you just parent a cleansing gel sprayer or paint_sphere to your gels to make them remove others? Sprayers have a property to suppress the particles and sound.

The sprayer gel reacts to physics slightly differently, so it would get out of sync. And if I used a prop_paint_bomb like with the Cleansing Gel the particles would get overlaid.
Just saw the other question above...I'd love to make the effect look like a normal gel, but the only way to place overlays or decals at runtime (without C++ code) is to lay them out over the whole map and then enable them when the gel gets near, which is what I was trying to avoid with this.
Would it be possible to make it look more like the vanilla gels, as in appearing as a decal on the floor rather than a 3D puddle?
Wait... did you mean the gelsplatter of the icygel, or the frozen water?
The Icy-Gel splatter looks even more like Gel than these stranges strings^^
But what is with the version the old video of the green and purple Gel use? why din't you use this?
For the Cleansinggel you may should make the cleansinggel for your Gels like one of you other Gels, that it just celans you Gels. than Mapmaker coould merge paintsprayergels with your cleansing, and your gels with paintsprayer cleansinggel and the Gels where able to overlape. if cleansinggel is neede just merge both celansinggel versions^^
