I was excited about Harlan at first, because I was hoping that it was a Lisp shader language. Instead, it's more like a replacement for generic computation on a GPU (OpenCL?). Still neat, but not in my area of interest at the moment.

tufty's been writing a cross compiler of lisp -> glsl

Scheme, actually :)

The basic idea is much the same as Harlan, i.e. a data parallel language from general purpose programming, but targetting OpenGL rather than OpenCL (this adds a few extra challenges, but gives a much larger "target base" of deployable machines - Raspberry Pi, my iMac's GPU, etc). It could also be bastardised to write entire shaders in scheme (that's pretty much the first hurdle).

It's here, and it's not usable (or even close to it).

@adam, re browser-fluxus, deffo. Bookmarked.
@tufty, if and when you get something working, I'd love to take a crack at it.

thanks, also new is this environment for algorithmic music coding: http://www.scripthica.com/ (choice of js or scheme)

Oooh, that's nice.

Uses biwascheme underneath for the scheme side of things, I'd guess the raw js implementation is a bit more efficient.

yeah, i think this generates midi files though so may not make much difference in most cases

noticed this today, might be one to make on an fpga:

We have designed and implemented a single-chip microcomputer (which we call SCHEME-79) which directly interprets a typed pointer variant of SCHEME, a dialect of the language LISP. To support this interpreter the chip implements an automatic storage allocation system for heap-allocated data and an interrupt facility for user interrupt routines implemented in SCHEME. We describe how the machine architecture is tailored to support the language, and the design methodology by which the hardware was synthesized. We develop an interpreter for SCHEME written in LISP which may be viewed as a microcode specification. This is converted by successive compilation passes into actual hardware structures on the chip. We develop a language embedded in LSIP for describing layout artwork so we can procedurally define generators for generalized macro components. The generators accept parameters to produce the specialized instances used in a particular design. We discuss the performance of the current design and directions for improvement, both in the circuit performance and in the algorithms implemented by the chip. A complete annotated listing of the microcode embodied by the chip is included.

the print on demand is really quick - can be 3-4 days from printing in the US to delivery, pretty impressive
