Ooohhh. That's bad.
sleep() is a static method that operates on whatever the current thread
happens to be.
Instead of
myThread.sleep(1000);
use
Thread.sleep(1000);
Otherwise you're liable to get confused about your threading.

Aha. That's the main problem that Joe pointed out.
Check the Java docs

So as you're increasing the offset, you're also increasing the size.
