I posted this over at the scsimulations.com forum, but thought I would add a note here.
Here are some textures to use for your panels in Helios to make them looking not so pristine. Just unzip the images into your My Documents/Helios/Images directory and then swap them with the embedded images. For the background image, make sure to set it to tile so it wont stretch. The textures are transparent, so that you can overlay them onto any base color for your panel.
Here is a quick preview:
