How does one write a big $\oplus$ sign?

Question

How can I write a big $\oplus$ sign? I've been experimenting with lots of different things like $Oplus$, but nothing is working.

You can try this:

\documentclass{article}
\usepackage{relsize}

\begin{document}
$\mathlarger{\mathlarger{\mathlarger{\oplus}}}$
\end{document}
