Posting here too since I got a lot of silence on pd-dev. From the README:
A tglgrid is a grid of cells that can each be toggled on and off. It can be instantiated with different dimensions depending on your project's needs. You can bang the left input to output a list of the active cells in the currently active column and send a column number to the right input to select the active column. Cells can also be toggled and/or turned on/off by sending messages: "tgl col row", "on col row", or "off col row".
Right now this has only been tested on linux. I would appreciate any reports about success and/or failure of running this in other environments.
The github page is here: https://github.com/nicklan/tglgrid You can find screenshots there if you're interested.
As this is my first external, I'm sure I've made some horrible coding/design mistakes and appreciate any feedback in that regard.
Cheers!
