<p>16-state joining is the simplest kind: It doesn't care about connections
between corners. It has 16 states because each of the 4 sides may be
connected or not, which is simply 2&times;2&times;2&times;2. Although
IconCutter describes this as "unfilled corners", really your icons can look
however you want. For many things you can get a good effect out of just 16
states.</p>

<p>The most obvious uses for 16-state joining include roads and pipes.</p>
