Having played with borders and not found one exactly right, I've come up with the following as a sample - using FilterForge's 'Film effect' (at minimally intrusive seting as I didn;t want it too stylised) and I've added the symbol of Keraptis - the arch 'villain' from the White Plume Mountain modules. There's a sample below. The scheme seems to work well, especially given a lot of the interior loadscreens are quite dark, and it's not too intrusive.
I feel I should also throw in the disclaimer, that there's several prefabs in use, albeit most modified to vary degrees - so I haven't suddenly become some mad area-baking fool...!
