There is a small mistake in your input syntax. When you want two voices to be 
polyphonic, you should either at least instantiate (one of) them as a \new 
Voice, or use the \\ voice separator. The first way looks like this:

\new Score <<
        \new Staff
        <<      \set Staff.instrumentName="Strange things"
                \new Voice {
                        \voiceOne
                        \relative c'' {as2~ as2}
                }
                \new Voice {
                        \voiceTwo
                        \relative c' {fis16 e16 d16 e16~ e4~ e2}
                }
        >>
>>

And the second way (which I often use when possible) (I'd also remove the \new 
Score and rather use the \score { } construct:

\score {
        \new Staff <<
                \relative c'' {as2~ as2}
                \\
                \relative c' {fis16 e16 d16 e16~ e4~ e2}
        >>
}

The \voiceOne and \voiceTwo commands are not necessary in this case, as the \\ 
voice separator creates this automatically. See:
