What about staring at a white wall? That always gives me blue and yellow blobs that dance and contract and expand, almost like spreading oil slicks. And static on top of it.
Your blue and yellow blobs sound cool - I hope they are not bothersome!
In response to migraine sufferers ... I get visual auras, but they are acute and pass. I have no idea if snow is connected to a predisposition to migraines. Though I am sure if I get my butt up to follow the link a poster kindly provided on this thread to show us a visual of snow, there is probably some good information there on this question

Thank you! I will look now
