In December 2011,  I revised the lever icons used on the Quaker Valley CTC panel to make the transparent background twice as wide.  This makes it much easier to touch the hot spot to activate the lever, whether it is defined as a two state sensor or as a multi sensor with left and right side activation hot spots.  It also works well with a mouse or trackball.  These icons were made part of the JMRI version 3.1.4 in the fall of 2012.  See the highlighted lever area (yellow box outline) on the screen shot below:

Two other images I have contributed to the JMRI project are the US&S Builders Plate and the "knockout" plug used in signal positions 12 & 14 above where only one side of the signal plate will be active.
