@yobink + @rbxbx, these are wonderful captures – I’m so glad y’all shared them here, thank you! they both showcase how versatile passersby really is. dang dang dang 
@gnome666 put an ephemeral call for clarification out there re: bits and why less concepts will sometimes stall out until a new rule / seed combo is selected, so that got me thinking about how to clarify these things in the interface.
the sequencing core of less concepts cycles through numbers by taking a user-input seed to start, then translating that number into binary and pushing it through the user-chosen CA rule. the rule morphs the binary, which is then fed back in as the new seed. if the rule/seed combo is productive, you’ll hear a looped sequence without any dead spots.
however, if a number goes through the CA rule and results in a 0, the sequence will seemingly stop because that 0 is fed back into the system – this outputs 0, which is fed back, which outputs 0, which is fed back, blah blah blah.
to help make things clearer, I’ve adjusted the interface on less concepts 2.0 (hoping to wrap things up this weekend):

the 1’s and 0’s in the bottom left are the current propagation of the original seed (01001110 = 78). 1’s and 0’s make for excellent gates, so the “bit” function just chooses which position in the binary number should produce sound.
in the new interface, the bar on the top is bit 1, the bar on the bottom is bit 2. this will hopefully make the options (+ process) clearer!
less concepts 2.0 will also feature a dedicated stereo delay/looper alt screen:

~ r e f r a i n is strongly linked to less concepts – it can be reset to a specified position in its 8 second buffer with the “bit” function while panning is determined by the notes played. this makes for a pretty neat polyrhythmic delay effect:
this script was made to address a really specific need for me, so all your feedback and questions really keep me focused on improving its legibility. 
hope this helps!
