Bloom's taxonomy drawn in Tikz

I'm in the middle of writing about various pedagogic theories for PCUTL (a higher education certification process) and I needed a picture of Bloom's taxonomy:

I needed to be able to play around with it a bit (so as to add annotations and colours like in the above picture) so I wanted something in Tikz. I found this helpful stack-exchange post for hierarchical pyramids and stole modified the code from there to get Bloom's taxonomy in Tikz. Here's the stripped down version:

The code is here (I modified the following slightly to give the above standalone image using the tikz standalone document class):

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{intersections}

\title{Bloom's taxonomy}


\begin{document}
\begin{center}

\begin{tikzpicture}
\coordinate (A) at (-6,1) {};
\coordinate (B) at ( 6,1) {};
\coordinate (C) at (0,7.5) {};
\draw[name path=AC] (A) -- (C);
\draw[name path=BC] (B) -- (C);
\foreach \y/\A in {1/Knowledge,2/Comprehension,3/Application,4/Analysis,5/Synthesis,6/Evaluation} {
\path[name path=horiz] (A|-0,\y) -- (B|-0,\y);
\draw[name intersections={of=AC and horiz,by=P},
name intersections={of=BC and horiz,by=Q}] (P) -- (Q)
node[midway,above] {\A};
}
\end{tikzpicture}
\end{center}

\end{document}

I put it up on +writeLaTeX as well: here.
