What's Subframe?
Subframe is a general name for technology that abuses particle update order.
Particle Order
Every frame in The Powder Toy, all the particles are updated one after another according to their ID.
When you hover over a particle with debug mode (use the "D" key to toggle) the ID is visible next to the X and Y values.
Every time you load a save, the particles are ordered from left to right and top to bottom. That means they will also be updated in that order (because the IDs are also ordered). You should always assume that the order of your contraptions can break when reloading the save.
Solid Spark
Solid sparks are used to activate powered materials every frame. It can bypass the spark cooldown (which is why spark blinks).
How to build it:
A solid spark is made using at least three particles:
1. Any element that can be sparked (like 
)
2. 
with the CTYPE of element one (if you place this while unpaused, it automatically sets the CTYPE, assuming there are no other elements nearby)
3. 
or a with a CTYPE of 
Their IDs have to be in this order to work:
ID of 1 < ID of 2 < ID of 3
How it works:
In the first frame, the 1st particle (the sparkable element) gets sparked by the 3rd particle (the or ).
In the second frame:
The life of the 1st particle (which is now a ) decreases from 4 to 3 and now can activate powered materials.
The 2nd particle (the ) replaces the sparked 1st particle with the original material, so that it's not sparked anymore.
Now that the 1st particle isn't sparked anymore, the 3rd particle can spark it again (thus avoiding the spark cooldown, so it doesn't blink).
So the 1st particle gets sparked, the spark is replaced with the original material, and then gets sparked again.
