First, let's start with the Life objects that make up the text "Golly". The text is made up of what is known as the “Light Weight Space Ship” or LWSS for short. These Life objects continuously move in one of the four directions — up, down, left or right but never diagonally. Their speed is often expressed as a fraction of “c” or the speed of light. The speed of light taken in the context of Life refers to advancement of one cell per generation and this is the fastest a Life object can move. | First, let's start with the Life objects that make up the text "Golly".

The “Glider” (mentioned above) can move only diagonally at c/4 whereas the LWSS can move orthogonally at c/2. We can easily verify this using Golly, running slowly enough to clearly see the movements of each generation. | The “Glider” (mentioned above) can move only diagonally at c/4 whereas the LWSS can move orthogonally at c/2.

Each letter is 9 LWSSs in height, except for the "O" which is 11 LWSSs in height. If you take a close look at the characters, not all LWSSs are in the same phase. Some seem to "point" downwards and the rest upwards. | Each letter is 9 LWSSs in height, except for the "O" which is 11 LWSSs in height.

At the left end, there are structures called "Eaters" or “Fishhook". Just flanked one either side by them are the patterns known as "Kok's Galaxy". | At the left end, there are structures called "Eaters" or “Fishhook".

Eaters are “Still Lives” which can eat away many objects without sustaining permanent damage. The job of the eater here is to assimilate the LWSSs coming in from the right. Since we have two distinct phases of LWSSs, the eater must be oriented properly to perform its job, otherwise the LWSSs will permanently destroy the eater. Kok's Galaxy belongs to the class of oscillators. Functionally, the generations of Kok's Galaxy flanking the eaters don't serve any purpose since deleting them doesn't affect the ticker at all. | Eaters are “Still Lives” which can eat away many objects without sustaining permanent damage.
