Let the FUN & games begin

There is no light without heat...
Some will fight, some will flee.
Consumer visual network for me!
Intel, AMD, IBM I want to watch 4 (at least) games streaming;
To my pixel dust lipstick screen gleaming!
While clicking pizza offer at halftime,
Vid-screening to friends and family distant,
Virtual world interacting and gaming too!
Don’t make me wait while fools debate,
Invest; in parallel and concurrently!

About the Engelbart Timeline Mural

A graphical chronology 1925-2015 of events that led up to/followed from Engelbart's 1968 demo.  By Eileen Clegg, artist and Valerie Landau, writer.  Signed copies of the mural (3' x 21') will be available for sale soon.

Thanks Matthew et al.

RE:
" ... I have to admit that just finding a good example was somewhat of a chore, which suggests either functors aren’t used a whole lot by OCaml programmers or nobody understands them. ... " Matthew Doig

" ... but compositionality is the core feature of functional programming. Ocaml style functors and Haskell style monads just aren’t possible in F#. Sure, we can simulate composibility, but the above example shows that it’s still too difficult. ..." Anonymous

" ... I’m just saying: it’s natural to be frustrated when translating a concept in one language to another that doesn’t have direct support for it. ... " Kurt

Is a good example of functors in OCAML, "Tilings as a programming exercise" by Guy Cousineau,  (Theoretical Computer Science 281 (2002) 207 – 217) [also with Mauny "The Functional Approach to Programming"]?

Trying to translate it to F# led to "The Haskell School of Expression, Learning Functional Programming Through Multimedia", by Paul Hudak.

Here's the conclusion:
" Now we can summarize the construction of tilings in one functor that takes all the necessary ingredients as parameters:
module Construct_tiling
(Group: CANONICAL_GROUP)
(Geom: GEOMETRY)
(GenMap: MAPPING with type source = Group.element
and type dest = Geom.transformation)
(GenColorMap: MAPPING with type source = Group.element
and type dest = Permutation.permutation)
(Tile: TILE with type transformation =
Geom.transformation * Permutation.permutation)
=
Make_tiling
(Make_generator_from_canonical
(Make_canonical_generator(Group))
(MakePair (Make_morphism (Group) (GenMap) (Geom.Tgroup))
(Make_color_morphism (Group) (GenColormap)))
(Tile)
This leads to a simplified graphical representation which appears in Fig. 3.
7. Conclusion
What we have obtained is a very generic program that can produce any tiling with a computable symmetry group that operate transitively on the tiles. ..."
