Here is mine....
I just switched from a Logitech keyboard with a display to a mechanical keyboard and was missing the media info.
So far, it is all about what I am playing in MediaMonkey. I tried putting on the MediaMonkey logo on it, though I couldn't find any place that did not make it look cluttered.
You can do some nice stuff with the "Sensor Image Graph" object and custom graphics.
I wish I was smart enough to write a real plugin for GOverlay/MediaMonkey, though my hacking with writing/reading an ini file seems to work fine. The time bar updates every second and I don't see to be killing my system with the constant writing/reading. Maybe I can create a RAM disk for the ini file. The last time I used a RAM disk was back when I had my home built 386sx powered PC in 1990. It looks like there is software to do that for Win 7.
It looks much better in person (colors, sharpness), my phone camera is not so good for this.
Like most of you (I am sure), I wish there were more font choices (sizes), the "square" fonts were just too ugly for me to use. I wish I could make the Album Name and Year smaller, oh well.
I also had to do some interesting math so I could centered data in the display (gotta like proportional fonts), though so far it is working well.
I also had an issue with the display going into power-saving mode, though it looks like a time object, hidden with black text on the black background may have done the trick.
Certainly worth the cost for me.
