JLambda is a fast, efficient, minimalistic, call-by-value, lexically
scoped Lisp or Scheme like language with closures. It is implemented
in, has exactly the same underlying primitive data types as Java, and
access to all of Java's built in packages and classes, as well as any
other Java classes found in the class path. It has an essential
component of SRI's Pathway Logic project, and comes as part of the IOP
framework distribution (qua iop.jar, currently weighing in at 1.8M).
It currently comes in two forms, as part of the IOP distribution, and
all the corresponding gui, graph and glyph support, and in a smaller swingless
version that is suitable for android (qua jlambda.jar, currently weighing in at 740K).
Both versions can be downloaded

binaries provides all but the android version.
