Tabletop Grace is a conversion of Tiled Grace for use with interactive touch
tables and is currently being tested on the Promethean ActivTable.

An extended version of Tabletop Grace that supports multiple devices and cross
device communication can be found here:
<https://multi-device-grace.herokuapp.com/mdg>
For the tabletop version:

The readme from Tiled Grace follows as much of the information is still
relevant. One caveat is that Tabletop Grace is recommended to be run in
Google Chrome only and even then the following setting:
chrome://flags/#overscroll-history-navigation
must be set to disabled.
This prevents touch actions from causing page swiping, i.e. forward and back.

Original Tiled Grace readme follows:

Tiled Grace integrates tiled and textual editing of code

To see Tiled Grace in action, go to
<http://ecs.vuw.ac.nz/~mwh/minigrace/tiled>.

To use Tiled Grace yourself, copy in a minigrace.js file to the working
tree root. minigrace.js can be generated from a minigrace.git working
tree with:
    make es
and will then be in es/minigrace.js. You will also need to copy in the
corresponding version of background.js (which changes only
infrequently).

You will also need to obtain the ACE editor from <http://ace.c9.io/> and put
all of its .js files into the "ace" directory.

Any of the sample dialects you want to use should be compiled with the
same version of the compiler:
    minigrace --target es -o sniff.js sniff.grace
Some dialects may require modification to be used in Tiled Grace rather
than the ordinary web interface. The sample programs themselves are
loaded from .grace files and do not need precompilation.

Because of browser security rules, Tiled Grace must be served over HTTP
to work. Either copy it into your web root, or run an in-place web
server such as osws:
    osws -I index.html -m -M .woff application/font-woff \
        -M .json application/json -d .

Tiled Grace works best in recent versions of Chrome and Firefox. The
transition animation tends to lag for large or deeply-nested programs in
Firefox, but the system in other respects tends to work slightly better
there.
