During this latest DreamHack event here in Jönköping (DHW23) I did some small updates to the Alertsquarer previously featured here. SG had bought some new hardware so instead of three 32×32 panels there was now two 64×32 panels.

So while fixing support for this, and doing some minor adjustments I also added support for loading and displaying PNG-images. Like the DreamHack logo in this image.
