Neat, another one to add to my collection: https://taoofmac.com/space/dev/lisp
(you can find most small LISPs there, reply here if you know more to add)
My Z3S5 Lisp[1] is rather big, it's intended to integrate well into Go programs, but it's based on the 1-page Nukata Lisp[2]. Go creates much larger binaries than C, though.
