Nicely done! - but..... I'd like to see how much separation between mask and HUD you could have before it became unreadable. Sure, if we stick a HUD to the outside of the glass of a mask we will be able to see it in wet cement, but it doesn't simulate whether you can see a HUD attached to a DSV, with maybe 5-10cm separation between mask and HUD, in bad vis.
Did you eat the soup after?
