Slightly offtopic, but I always laughed at these types of animations in hacker movies. Until one day I made a tool to extract strings (mostly passwords or hashes, purely for academic purposes!) through SQL injections in SQL Server when the error message did not return anything useful. I scanned each character bit by bit and depending on the value, I would either return control immediately or delay the response by a couple of hundred ms. That allowed me to reconstruct the string bit by bit, and as new information was acquired for each character - it would change on the screen. It looked exactly like some of these hacker movie scenes... =)
