[buttERSON]

Ok so I'm trying to solve this riddle.. it shows this picture

_________
L | i

the L|i is colored blue.

The hint is "You must have something like this on the walls of your house"..

So far it's not ..
Switch, light switch, plumbing, pipes, electricity, copper, frames, pictures, art, brackets, ceiling, weight, pounds, roof... Help me I'm stuck...

L | i

This isn't a picture.. its supposed to be a shape. The "L | i" is colored blue.. Something that has this shape..

A shelf perhaps?

I dunno drawing pictures with text is the lowest form of art.
