That site makes no sense at all. Did anybody actually read the copy?
At the top it says "Only One Amiga" but then it shows the all-in-one keyboard "Amiga", and the box "Unit Amiga Core" aka "Unit Center Amiga".
"SUPER A.G.A. HD" - orly?
"Retractable Keyboard" operation shown in the 6th image down. Okay, what purpose does this serve? So when you get tired of flipping up the back in "open" position you can "close" it to a more stable configuration?
The large lighted port on the back is designated as the "LUA (Link Universal Amiga)". Okay, so in addition to creating a SUPER AGA HD chip he's also going to create a proprietary connector and I assume protocol. Perhaps to connect to the rather ambiguous "Unit Amiga Core"?
"Grid Area" - for those times you want to get on the Grid. You've been on the Grid, right?
Seriously, there's nothing going on here except some guy practicing his rendering skills.
