Apologies for x-posting. (resending because apparently the original was
rejected because I was "not subscribed?"...)


It is my great pleasure to announce immediate availability of the latest
Pd-L2Ork, its K12 module, as well as the latest version of Pd-L2Ork for the
Raspberry Pi platform that includes comprehensive set of objects for
sensing, including GPIO with pulse-width-modulation support, and analog
sensor monitoring support (via MCP3008 A/D chip and SPI module). In addition
to a slew of bug-fixes and improvements, pd-l2ork's structures have seen a
significant overhaul (thanks to contributions from Jonathan Wilkes and
others) now supporting a majority of the SVG spec and allowing for some
powerful manipulations of structs inside pd patches. Please note that the
structs are still under development, so some instabilities remain. Other
notable Changelog Highlights for this release include:


*new drawimage and drawsprite structs

*improved classinfo, canvasinfo, and pdinfo objects

*xapian-based browser

*proper queuing for all iemgui objects and other improvements

*New preferences dialog

*New customizable arrays and jump-on-click ability

*UI themes

*Improved sanity checks for graph-on-parent patches

*over a hundred of other bug fixes and improvements


For a complete list of changes please consult the attached git-extracted


The new release is accompanied by a comprehensive documentation on how to
connect RPi to the computer as well as run and configure Pd-L2Ork (and its
K12 module) for operation on RPi. In addition, as part of this release, the
regular Pd-L2Ork install instructions have been also streamlined to make
them easier to navigate.


For those in Virginia Tech area, the new release candidate will be showcased
at the upcoming Institute for Creativity, Arts, and Technology community
meeting this Friday 830-930am in ICAT Sandbox.

A contemporary intermedia ensemble, L2Ork, thrives upon the quintessential
form of collaboration found in the western classical orchestra and its
cross-pollination with increasingly accessible human-computer interaction
technologies for the purpose of exploring expressive power of gesture,
communal interaction, discipline-agnostic environment, and the
multidimensionality of arts. In addition to furthering the artistic
exploration of the newfound genre, the ensemble's particular focus is on
integration of Taiji (Tai Chi) choreography into its performance practice as
well as its philosophy.


Founded by Dr. Ivica Ico Bukvic in May 2009, and since 2014 co-directed with
Dr. Charles Nichols, L2Ork is a part of the interdisciplinary initiative by
the Virginia Tech Digital Interactive Sound & Intermedia Studio (DISIS) and
the signature initiative of the newfound Institute for Creativity, Arts, and
Technology (ICAT). As the world's first Linux-based laptop orchestra L2Ork
offers optimal infrastructure for creative research at minimal cost. By
providing a seamless integration of arts and sciences it is in part designed
to bridge the gap between STEM (Science, Technology, Engineering, Math) and
the Arts, with particular focus on K-12 (Kindergarten to 12th grade)







Pd-L2Ork is a Linux-centric fork of the legendary Pure-Data. With over three
years of development and 700 new features, bug-fixes, and improvements, its
focus is primarily on the laptop orchestra environment, and more
specifically L2Ork setup. In 2012 Pd-L2Ork introduced unique K-12
educational module, offering GUI-centric granular approach to learning
Pd/Max-like programming environments using a collection of abstractions
geared towards K-12 students. Most recently, Pd-L2Ork is also supporting
Raspberry Pi platform, paving way towards sub-$100 laptop orchestra







Best wishes,
