Is rotation of symbols around the y axis possible?

Question

Is there a way to rotate a symbol any positive degrees around the y axis? The y axis is here taken as the one perpendicular to the text line and lying in the text surface. E.g., an I would loose its bars with such a rotation of 90 degrees and would be indistinguishable from an O with the same rotation.

Answer 1

Here is a TikZ solution:

\tikz\node[xscale={cos(\angle)},inner sep=0]{Texte};

Examples:

Code:

\documentclass{article}
\usepackage{tikz}
\begin{document}
Texte%
\foreach \ang in {0,1,...,8,9}{%
  \tikz\node[xscale={cos(\ang*20)},inner sep=0]{RI\ang};%
}...
\end{document}
