What if there was was Playstation Move extension on Scratch? Yes, I have done an project that is compatible with Playstation Move, but it only really suported button presses. In this extension, gyro and accelometer is suported. Here is the block list:

<[Is controller [Controller 1  v] conected?\]>
<[Is button [Menu button  v] pressed on controller [Controller 1  v] ?\]>
(Gyro [X  v] on [Controller 1  v])
(Accelometer [X  v] on [Controller 1  v])
([Controller 1  v]'s [X  v] position)
(Trigger pressed % on [Controller 1  v])
Set ball color to [#ff3333]

Maybe this idea/extension will make into Turbowarp!?

if <(username) is an friend> then 

  
say (join [Hello, ] (username))

else
if <(pick random (1) to (2)) = [1]> then 

  
say [Hey! Wanna be friends?]

else
say [Did you know that nobody asked?]
end
end

Try finding something about using playstation move in javascript, beacuse scratch extension are based on javascript. You can code it in javascript itself or use raw blocks in extensions creators.
