In signal circuitry, a transparent object is one that is completely destroyed by the passing signal, then rebuilt. Often (though not always) it is associated with a transparent debris effect, a reaction in which an active region destroys a still life, then later, having passed through the place occupied by still life, recreates the still life in its original position.
Many common objects have been found to be transparent in certain reactions.[1] A brief list of examples include:
- The block in conduit 1, Fx77, BNE14T30, etc., as well as the specifically named transparent block reaction shown below.
- The beehive in one of the century eaters, one of the variants of SW-2, BRx46B, etc.
- The loaf in RF48H.
Transparent block reaction
The transparent block reaction is a certain reaction between a block and a B-heptomino in which the block reappears in its original place some time later, the reaction having effectively passed through it. It was found by David Buckingham in 1988. It has been used in some dependent Herschel conduits and in the gunstars.
