{samcarter} {The \code{tcolorbox} inner beamer theme} {The \code{tcolorbox} inner beamer theme is a new theme for the beamer class. It replaces normal beamer blocks with \texttt{tcolorbox}es of the same look and feel. This allows users to easily modify the appearance of blocks. In this short talk, I will give a short overview of the theme and show some examples of how one can customise blocks.}
