Here's my partial list, of what I can remember at the moment, and in no particular order.

1) Opa

"Opa is a concise and elegant language for writing distributed web applications." - http://opalang.org

"Opa is an open source programming language for web applications." - http://en.wikipedia.org/wiki/Opa_(programming_language)

There is much to say about Opa. I recommend going through the references in the Wikipedia article.

2) BaCon

"BaCon is a free BASIC to C converter for Unix-based systems. BaCon intends to be a programming aid in creating tools which can be compiled on different platforms (including 64bit environments). It tries to revive the days of the good old BASIC." - http://basic-converter.org

BaCon is interesting because: 1) all you need is a shell and a C compiler, 2) it was created by Peter van Eerten, who also made GTK-server, and 3) it converts lazily, effectively making a BASIC-like wrapper for C, thereby allowing easy access to some of the more interesting aspects of C, which would not normally be available in BASIC.

3) Spin

"Spin is a multitasking high level computer programming language created by Parallax's Chip Gracey, who also designed the Propeller microcontroller on which it runs, for their line of Propeller microcontrollers." - http://en.wikipedia.org/wiki/Parallax_Propeller#Built_in_SPI...

4) Agena

"Agena provides you with all the means you need to implement your ideas quickly: fast real and complex arithmetics, efficient text processing, graphics, flexible data structures, intelligent procedures, simple package management, plus various configuration facilities in multi-user environments. The syntax resembles very simplified Algol 68 with elements taken from Maple, Lua and SQL. Agena is based on the ANSI C source code of Lua." - http://agena.sourceforge.net

5) Monkey

"Monkey is a brand spanking new programming language that allows you to create apps on multiple platforms with the greatest of ease. Monkey works by translating Monkey code to one of a different number of languages at compile time - including C++, C#, Java, Javascript and Actionscript." - http://monkeycoder.co.nz

"In 2011, BRL released a new cross-platform programming language called Monkey and its first official module called Mojo. Monkey has a very similar syntax to BlitzMax, but instead of compiling direct to assembly code, translates Monkey source files into source for a chosen language, framework or platform." - http://en.wikipedia.org/wiki/Blitz_BASIC#Monkey_and_Mojo

6) LOLCODE

"LOLCODE is an esoteric programming language inspired by the language expressed in examples of the lolcat Internet meme. The language was created in 2007 by Adam Lindsay, researcher at the Computing Department of Lancaster University." - http://en.wikipedia.org/wiki/LOLCODE

7) Neko

"Neko is a high-level dynamicly typed programming language. It can be used as an embedded scripting language. It has been designed to provide a common runtime for several different languages. Learning and using Neko is very easy. You can easily extend the language with C libraries. You can also write generators from your own language to Neko and then use the Neko Runtime to compile, run, and access existing libraries." - http://nekovm.org

"Neko is a high-level dynamically typed programming language developed by Nicolas Cannasse as part of R&D efforts at Motion-Twin." - http://en.wikipedia.org/wiki/Neko_(programming_language)

Neko is one of the targets for haXe, and was created by the same guy. Neko is six years old, but given its importance, I think that's close enough.

8) Piet

"Piet is a programming language in which programs look like abstract paintings. The language is named after Piet Mondrian, who pioneered the field of geometric abstract art." - http://dangermouse.net/esoteric/piet.html

"Piet is an esoteric programming language designed by David Morgan-Mar, whose programs are bitmaps that look like abstract art. The compilation is guided by a "pointer" that moves around the image, from one continuous coloured region to the next. Procedures are carried through when the pointer exits a region. Piet was named after the Dutch painter Piet Mondrian." - http://en.wikipedia.org/wiki/Piet_(programming_language)

I don't know the age of Piet, but the 99 Bottles of Beer example is from just over five years ago.

--------------------------------------------------

Before anyone complains, the article says:

"In this post I will provide a list of fairly new languages (let’s say 5 years with a little flex) that display interesting features and display higher-order thinking in the way that they tend toward an evolution of past learnings in programming language thinking. Not all of these languages enjoy active development, but the more important point is that they represent in some way "new language thinking". Remember that this goal does not necessarily mean "innovative"."

I think that each of the languages I've specified applies, although, for some, my interpretation of "evolution" may have been a bit loose.
