These Beamer themes have been around quite a while, but I’ve just discovered them from some Japanese github sites.
The Blackboard theme may be useful for short talks with a little bit of fun:
\documentclass{beamer}
\usetheme{Blackboard}
\usetheme{Blackboard}
I’ve a feeling that this DarkConsole theme would be popular with some developers.
\documentclass{beamer}
\usetheme{DarkConsole}
\usetheme{DarkConsole}
And the Moreblue theme has a nice, airy feel about it:
\documentclass{beamer}
\usetheme{MoreblueLight}
\usetheme{MoreblueLight}
