Actually we can make a nice definition using the RL typesetting ... as
not that many fonts have a proper aT kerning we can do the following:

\def\LuaTeX
{\begingroup
Lua%
\setbox0\hbox{oT}%
\setbox2\hbox{o\kern0ptT}%
\ifdim\wd0=\wd2
\setbox0\hbox dir TRT{To}%
\setbox2\hbox{T\kern0pto}%
\hskip\dimexpr\wd0-\wd2\relax
\fi
\TeX
\endgroup}

Of course this ignores the fact that the a is not symmetrical which is
why we use the o instead  but it looks impressive (as the T normally is
symmetrical we don't really need the need the dir).

Maybe I should write an article about it (as i've seen quite some
articles / talks about how complex it is to do tex related logos) ...
