Sample programs in the Piet programming language
dangermouse.netFor those using Piet in production, what async web framework do you favor? Warhol seems pretty popular, but Schiele has me impressed with its expressiveness. We're currently using Dali, though I'm a bit dissatisfied at how surreal its API is.
I'm using Monet, because I want to make an impression on my clients.
We just throw some Pollock on the box at random, but there's some more detailed Seurat dotted around the stack.
I'm not familiar with the others, but Dali is my choice for surreal-time operating system development.
We are using Apache Van^Gogh. But it's trendy to use Hirst though.
Love Van^Gogh in combination with a Munch cache. Recently went to the Van^Gogh conference where they had a great talk on this topic. [0]

I really love this kind of conferences, where things are almost hands-on and you can see the actual source code of all(!) presented projects.
They even embrace showing source code, and all discussion is centered around a specific piece of code.
These are qualities I miss at most conferences.
I suspect this is being downvoted because VG has a reputation for being notoriously unstable.
We get popular results with Banksy, though come to think of it, not sure if anyone knows who our programmers are...
I'm surprised async web framework as old as Warhol, Schiele or even Dali can keep up with the modernities and constant advances of JS and html5. Aren't they too old-fashioned?
And how can Dali be more surreal than using a language designed to animate monkeys on webpages for writing full-blown applications?
I prefer the Hundertwasser framework, developed by 100water. Not sure how they achieved that, but this framework almost forces me to produce beautiful code.
You should definitely try Pollock. It's a bit rough, and the code is messy and hard to understand - but very powerful.
I've had good results from Emin. But it can be a bit temperamental.
I was little terrified after reading the first sentence...
Do you have references for these? Google doesn't give me much.
Salvador Dali is the full name. I'll let you decide how serious it is.
Just having a little fun, friend. :)
An "actual" piet quine:

I had an interesting time writing a JIT for Piet some time ago. Piet is a pretty weird language in a few non-obvious ways. From what I remember:
* Execution moves between blocks of colour. Flood fill algorithms are a valid compiler optimisation!
* Execution can move left/right/up/down. You can't necessarily tell what will be executed without doing it. The 'codel chooser' stuff means you can exit a colour block in two different ways depending on program state (plus left/right/up/down, so 8 ways total...).
* Instructions are encoded in the difference between colour blocks.
* Piet is otherwise a fairly straightforward stack machine.
I wouldn't trust these programs to work. The fibonacci one certainly doesn't.
When the explanatory line in the fibonacci example first hits the left hand side of the program, the Direction Pointer appears to be being rotated anti-clockwise.
Were it rotated clockwise, as-per the spec, it would go up, hit the black block above, and eventually end up in an infinite loop.
The command executed on entry to that block is PUSH (pale to normal yellow), so it shouldn't have any effect on DP.
I'm wondering if there is a practical use of such a graphic language. I am thinking of printing the pictures associated with the code, put them somewhere, and other people could take some photos of those pictures with their smartphones and run the corresponding code. That might be useful for a game but I can't think of anything yet.
Like a qr code but without needing internet. Could be cool for geocaching
QR codes don't need internet. They just get less reliable the bigger you make them, so often people just put URLS in them and put the real info at the URL. There are plenty of "historical site" QR codes around here that have a short paragraph of info in them.
I was going to attempt a humorous comment of "I prefer a language that supports recursion, so I use Escher". But then my brain went, "think there already is an Escher". There is one, it's from 1995.
Are programming languages about to hit the same problem as musicians, thinking up that cool but unused band name?
The Pi calculator gave me the rest.

> Richard Mitton supplies this amazing program which calculates an approximation of pi... literally by dividing a circular area by the radius twice. Richard says:
The output is printed without the decimal point after the 3. Naturally, a more accurate value can be obtained by using a bigger program.
