i know some of these have already probably been done, but i'm posting them anyways.
Computers using Projectiles/Relays
Including ALUs, CPUs, maybe even some sort of 1x1 print screen with a GPU.
It'd probably not be worth it or maybe not possible, not sure. I'm tired right now, it just seems like an interesting concept.
They obviously wouldn't be powerful, and not at all very useful for anything, but they'd be really neat if possible.
I have seen Halcynthis make a sort of Paint program using somewhat complex logic relays, but it was pretty dodgy.
Memory
Somewhat like the above. Memory using projectiles or relays. May not be possible, just a neat concept.
Calculators
I've yet to see a well-working calculator on Blockland. I'm sure it's possible.
Transformer sort of thing.
"Transformer" may not be the word I'm looking for, basically what I mean is a contraption that allows you to play a wide variety of sounds using relays or projectiles. It's been done before, but only in simple ways.
Random Number Generator
Seen it done a few times, but again, in simple ways.
the above are ideas, i just think it'd be interesting to see these done, looking back, i've seen some pretty complex arcade games using only projectiles.
i got to thinking what we could do with even more complex networks of similar things, maybe make a computer that isn't simple as duplicating a plate into a slot and having the computer run off that.
I'm tired, I may not even remember making this thread in the morning.
Would these be possible, and if so, who would participate in making some of them?
