LTK was written by Peter Herth.
Many examples, covering the tkdocs tutorial, were contributed by Peter Lane: https://peterlane.netlify.app/ltk-examples/.
Plotting with Ltk
A wrapper around tklib's Plotchart library is also available here: https://peterlane.netlify.app/ltk-plotchart/.
IssuesOne unfortunate problem is that LTK mysteriously fails to run on some Windows computers, depending on what programs happen to be running in the background. People are encouraged to either donate a Windows box for testing, or helpfully volunteer to track the issue down.
This may be an issue limited to certain Lisp implementations, as SBCL has not been observed to manifest this problem.
