Legos
Although the world would normally associate the Lego with the cute interlocking plastic boxes first developed in Denmark in the 1940s by Ole Kirk Christiansen, Lego has taken on a pretty different meaning in today's standards and for the scenes that take place at AfterDawn.
A Lego when referred to in a digital media environment is a slang term that describes the little digitized boxes that appear in your encoded or decoded video after a bad conversion or burn. This can happen when media is burned too quickly, conversion is not done properly or takes away too much of the the original data integrity or simply a bad disk.
