Other (as stated in the work)
This Blackboard beamer theme and template was created by Kazuki Maeda <firstname.lastname@example.org> for Japanese presentations, but can be used for English (or other European languages) presentations as well. It has been modified to work with XeLaTeX.
p/s: The blackboard background was drawn with TikZ; the code is also included in the template.
