I like the effect on the images used on this  page, and out of curiosity I'm trying to replicate it in Illustrator. It's not a simple multiply mask, and seems a more involved than the kind of duotone I can do in inDesign.

I was going to add a bit of information to my post on a previous day using schematics and some instructions. What programs are being employed for this purpose?  I mostly want to see what others are using and that I can easily use to give descriptive schematics.  In a perfect world, and I know this is a case of me wishing, it would be:   Free. Extremely easy to draw schematics in. Allows simple production of waveforms for the inputs/outputs.

Like this:  .------&lt;------. |             | v             ^ |             | '------&gt;------'   I am currently using  \begin{scope}[very thick,-&gt;]   \draw (-4,1)--(-4,0)--(0.1,0);   \draw (0,0)--(4,0)--(4,1.1);   \draw (4,1)--(4,2)--(-0.1,2);   \draw (0,2)--(-4,2)--(-4,0.9); \end{scope}   but this is rather inelegant. I prefer something more like  \begin{scope}[very thick,middle decoration=&gt;]               %           ^^^^^^^^^^^^^^^^^ a hypothetical option   \draw (-4,0)--(4,0);   \draw (4,0)--(4,2);   \draw (4,2)--(-4,2);   \draw (-4,2)--(-4,0); \end{scope}
