From reading the questions in the Beginners area... Sheeze whats the title of someone who has not reached the level of a beginner yet - Someone like me. :(

Anyway would someone please explain whats going on in this experiment with "Flip" and "Cls".
Am I looking at some potential tricks or is this just stupid.

Graphics 640,480

For n=10 To 100 Step 10
'Cls

'FlushMem; Flip

If n Mod 4 <> Null
SetColor 255,0,0
Else
SetTransform 10,1.3,1.04
SetColor 0,255,0
EndIf

DrawRect n,n,100,50

SetTransform 0,1,1

FlushMem; Flip
'Delay 400 'Added to help see the effects
Next

WaitKey

rem
First run with Cls, Flip and Delay commented out
Remove comment from Delay only... then run. This allows time to see effect
Remove comment from Flip and Delay... then run
Remove all comments... then run
Add back the comment to Flip... then run
end rem
Appreciate your comments,
Thanks
