Useful or Useless?

[Zero Tolerance]

Another eventful (not) day in my life and i find myself creating yet another 'thing' which is pretty much useless to me but kept me occupied for the time i was making it.

Basically this 'thing' which i can only call an image-slicer will allow a user to upload an image, and slice 'n dice it then output the image into lots of squares inside a table, once loaded it will look like the same, but it is actually seperated into 225 equally sized squares.

But as usual, i have no use for it, and i was wondering if anyone here had any ideas they think it could be used for, or if they would like to try it out i have attached the code below, granted it is messy, since it was just a doodle, just upload it into a directory , like '/slice', and inside the directory make a new directory called 'cave' and CHMOD it to 0777, inside the directory 'slice' upload the slice.php posted below.

Note: Required GD lirbary, and supports jpg/png/gif images.

So, any ideas, or is it completely useless?
