terminal glasses

Ok so I have this code: http://pastebin.com/00rKNwWc

I dont have any idea how to make the animation go smoother unless I reduce the sleep time to 0.00001 which is obviously bugging the glasses.

Maybe you can help me , guys?

The animation method:

m = peripheral.wrap("top") – which is the terminal glasses bridge
modem = peripheral.wrap("left") – which is the modem
width = 150
height = 50
function animation()
for i = 1,50 do
m.clear()
m.addBox(10, 10, width, height, 0xFFFFFF, 0.5)
width = width - 3
height = height - 1
sleep(0.1)
end
for i = 1,50 do
m.clear()
m.addBox(10, 10, width, height, 0xFFFFFF, 0.5)
width = width + 3
height = height + 1
sleep(0.1)
end
end

Don't clear the glasses. If you can set new coordinates for the box, do that. Otherwise, it's just going to flicker. You also can't get reliable sleeps much shorter than 0.05s in practical terms, IIRC.
