For this week's MMM challenge I've got a lot of explaining to do for it to make sense to everybody...
Top left: This is a rephrase of "There is no place like home". Without being too technical 127.0.0.1 is described as the adress of your own computer in a network.
Top right: As all math professors know (and don't you count me in in that category, on the contrary *ha ha*) the binary system consists purely of zeroes and ones, which represent a numeric value... So it doesn't say ten but actually two kind of people.
Bottom left: Many of you have heard the old childhood rhyme" Roses are red, violets are blue... Instead of the colours I have put in their hexadecimal value in their corresponding colours.
The rest, I believe, is simple addition... Hope, I explained it so you didn't get more confused :-)
Oops, I just realised, the stitched one cross the brown is hard to read. It says: "2 + 2 = 5 for a high value of the number 2" :-)
The green areas are white paper, I have inked green with an ink pad.
