Block

Blocks are place-able objects that affect your world in several various ways. They do not hold an inventory. However they do have many other properties which fall into a few broad subcategories;

Path
Paths alter the movement of units and/or items. They are usually not stack-able on their own.

Structure
These blocks occupy physical space and may alter walk-able and build-able attributes for paths placed on top of them.

10 type of blocks like these: 5 type of crystal blocks available in beta recently:

Logistics
These blocks can dynamically modify the flow of workers or items on underlying paths. They are placed as overlays on top of structural blocks or paths.

Computation
These blocks act as sensors for world data or accept inputs from other blocks, perform specified calculations, and send out an output value. They can be chained together to create complex functions. From ver.130, Math Block can be copy.

Steam Pipe
These blocks can only be placed upon the steam pipe (Default-Key: T)

Mana Pipe
These blocks can only be placed upon the mana pipe (Default-Key: G)

OmniPipe
These blocks can only be placed upon the Omnipipe (Default-Key: ) The transport speed is 3.3/3.7 per tile/sec(measured by 10s/20s,10 tiles)

Farming/Mining (Function)
These blocks are laid on the ground and alter the properties of buildings which are nearby them. They are usually not stack-able.

Decoration
These blocks are mainly available to offer a sense of creativity and does usually not offer functionality. Even though you can use fences and walls to prevent workers from interacting with buildings. This comes in handy with unfiltered barns or silos.
