I personally would prefer having glue as long as you can remove it. If theres no removal then the big particle sounds better. Just in my opinion.

Do you have the link?

And the projectile thing I was talking about...
Why just limit it to one particle? It could be an entirely new function!

Like holding down ALT + SHIFT (Line tool) Would allow you to launch a bunch of particles with the length of the line being relative to the velocity at which it is launched.

why not forget about the glue, and have a whole section filled with movable objects, then you could make pullies, pistons, falling anvils of death, elevators, cannon balls, bullets, maybe even a smithy! I think having movable objects would be awesome! a few nights ago, I could think of hundreds of different applications. if given permission, can I add a longer post of ideas and the advantages?

If you want to do those things, you can just use oe-cake. Still, I like the idea of solids that aren't glued to the background.

yea, for some people, oe-cake doesn't work, like on my comp. and on other physics engines, they're just too laggy.

something with explosive qualities or the ability to interact with particle blocks for example. particle A traveling at 2300 FPS + air movement = particle A using air to move other particles out of its way just like a .50 cal does when it hits a target, the bullet never actually touches you its the air pushed out of the way that kills you

yea, and since different materials have different wieghts and densities, you can have a whole slew of materials! some metals previously rejected, might be accepted because it's not just conductivity, there's how fast it falls, how hard it falls, and how fast and strong something has to be to cut through it! (just think, a harpoon gun!)


--EDIT--

Since there's really long delays between posts, I'm just going to list off some ideas, and why.

1. Lead-very heavy, low melting temp, but very soft and easy to cut through with other materials, no conductivity changes, for any of these

2. Iron-basically metl, just movable, just the same.

3. potassium-extremely soft, easily cut, I don't know the weight, it violently reacts with water.(weaker than rubidium)

4. mercury-low freezing temp, just as conductive as iron, but just a tad thicker than water, maybe bomb trigger?

5. tungsten-high melting temp, rediculously strong, basicly the thing you'd use in an engine, weight unknown

6. aluminum-very light, average melting temp, somewhat soft.

7. Ancr-just something to hold it up if needed, just like mini wall, or diamond.

8. thread/rope-great for pullies, burns just like wood

9. cable-like rope, but stronger and is steel

10. steel-slightly stronger than iron

11. A grab tool, so you can pick up the objects, and handfuls of powder and such

12. some form of movement, like a moter that can make some things like gears spin.

also, since in real life most metals are softer and glow when heated, things like iron, steel, tungsten, could glow sorta like fire and get softer before they actually melt, indicators for smithing for fun. It would be even more awesome if you made things like wood, plant, and some electrical things move too, so you can just "drop" a circuit board in a slot, and have houses and building collapse when you hit it in different places! more suggestions the better! =D
(wow, longest post ever^)
