Just wondering if anyone else thought that the cursor on the computer screen looked a little odd...
Looked a little sinister... almost like a monster.
I think that's just a nice side effect, not an intentional representation of a monster.
Most old computers had some kind of prompt to let the user know input was needed.
For example, in DOS, the prompt was usually C:\ >. But drive letters themselves are a relatively new development as well.
Pre-90s computers often had a prompt that included symbols like : = >. They were also often something like COMMAND:>
Plus, emoticons as we know them today didn't exist in the era that computer seems to have come from. =)
