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) ...
