@m4ster r0shi,
This used to be a nice neighbourhood >:(
But anyway, no, that wouldn't be very easy. Although I could move the monitor down to the floor and sit on the floor where I can't be seen... but that would be suspicious, not to mention impractical.
You can turn off the monitor and print a random image, then you can move to a safer place
Or you can buy a monitor lizard as pet and have fun with that instead that with your hands
In order not to raise any suspicion, you could take some pillows, tie them to each other with something and place them on your chair in a way that one could easily confuse them with you if seen from outside. A flashlight pointing at the pillow-head would serve well as a screen.
As for the practical problems, well, since nobody has a clue about what you're actually doing, I guess you can take your time to solve them in any means you find appropriate depending on your mood, overall structure of your room, accessories available etc... be creative ;)
I like titties....also I like the feel of grain the screams of a man in pain blood coming down like rain showering me! That everlasting thrill during the final kill body dumped in a land fill got off scott free...These are all the little things that make me smile, this is all the stuff that makes life worth while! One day I will eat your brains and it will be great so let's sing about the things we like and meet your fate!
tl;dr I'm a serial killer :D and kudos to who ever gets the reference.
