Inspiration:
I was given the opportunity to continue the #tweetcart_relay from @Alexthescott's "entropy lock pick" (TEIA OBJKT #752033)
Like Alex, I wanted to preserve two major features from the original carts. Entropy Locking (reducing the entropy of a generative piece using seeded pseudo randomization) and using screen data as a sprite-sheet to be re-drawn to the screen (causing a sort of feedback loop). The main changes I wanted to bring to the table was experimenting with *what* is drawn to the screen (and where) aswell as applying a fresh new palette.
What is a Tweetcart Relay?:
We receive a tweetcart as a 1/1 from a friend, and we modify it to make our own tweetcart, which we then send to someone else, to continue the process. Eventually it's our hope to have many relay chains going on with many people, anyone at all who likes to make tweetcarts or wants to learn how :)
Suggested Relay Guidelines from myself:
-> Copy the prior tweetcart 1:1, and tweak the cart while keeping some part of the original program until you've left your aesthetic changes however robust, and pass it on
or
-> Copy just a portion of the cart and build new, before passing on the tweet

Explanation:
```
-- using @2dArray's excellent Palette-Maker
-- https://www.lexaloffle.com/bbs/?pid=68190
?"\^!5f10🐱☉8웃9:♥⌂;⬅️3⬇️1▒"
-- store keywords to save chars later on
-- srand resets the random seed
-- poke will let us adjust Pico-8 Memory values
r,p,q=rnd,srand,poke
-- get and assign random seed value
s=r(-1)
p(s)
-- f will be an incrementing value from 0-4
-- helping us 'pick the entropy lock' by getting a new seed value
f=0
-- set the screen memory as the spritesheet with poke()
q(0x5f54,0x60)
-- mirror the screen from left to right with poke()
q(24364,5)
-- assign a random start color
cls(r(16))
-- label for GOTO statement
::_::
-- every frame, print 16 characters down on the left side of the screen
-- ? is shorthand for print, and z is the character to print to the screen based on the y position
-- print the color of the given x,y coord + 1 modulo 13,
-- this will loop through all 14 (since 0 is included) colours in the palette
for i=0,16do
x,y=r(65),r(127)
z=16+y/16
?chr(z),x,y,(pget(x,y)+1)%13
end
-- if random value is high enough, lock entropy by resetting the seed
-- randomly feed-forward a part of the display (I decided to go in more than alexthescott did)
if(r()>0.8)f+=1p(s)sspr(r(6),r(6),122,122,0,0,128,128)
-- every 4 locks, increment the seed by 1 (this produces similar results to generating an all-new seed but is less characters in the long run)
if(f>=4)f=0s+=1p(s)
-- animate at a "smooth" 30fps
flip()
-- return to the GOTO label (causing infinite loop)
goto _

To Friends and Creators:
Want to change the code, or make a relay Tweetcart of yourself based on this one? No problem! You can find the official education edition of the Pico-8 here, for free, usable in the browser, thanks to the Pico-8 Creators lexaloffle & co: https://www.pico-8-edu.com/ . Simply press escape to get to the code editor, copy and paste the source code here into there, and press ctrl+r to run the pico8.
All of my social media can be found at carsonk.net, but I am most active on Twitter @CarsonKompon. Feel free to reach out if you're interested in learning more about PICO-8 and generative art as a whole :)
