well wireworld has a much larger purpose than 'making giant blocks'. Its similar to the gam of life elements that we have. Example: if an 'orange wire' is surrounded by one or two white pixels (electron heads), it turns into another white (head). After two frames it turns back into an 'orange' (or copper). Wire has to be layed out in specific ways so it acctually serves a purpose (example: logic gates).

what can you do with logic gates though?

I'm only somewhat aware of logic gates and i've never really used them. The definition for logic gates i think is being able to take various inputs and computing them into a singl output, example:
-Simple ones allow passage in only one direction (like PSCN>NSCN)
-More complex ones allow a constant stream of outputs with one input, and no output with another input (similar to battery, switch, pscn and nscn)

but i mean what uses could there be at all?

Take a look, every save that has some kind of electronic will probably have a one logic gate or more. Bigger ones include:

im trying to make a counter with it now
here take a look

And here's some logic gates.

I have updated the wiki, check it out, see if I got everything.
