The Expedit bookshelves and Lack tables have to be some of IKEA's most popular products. I should know -- I own a piece from both series. As such, the internet is stuffed full of mods for these particular items. Usually, such mods err on the side of increasing practicality. This one, however, is all about style.
The now-butchered table reminded its creator -- an Instructables user with the handle "BrittLiv" -- of the TV show Dexter (or perhaps the novels upon which the show is based) and so inspired, they decided to paint the visible cuts red and slap a quote from the series on top.
The modification itself is straightforward, as long as you don't mind a bit of cutting. The key points are to reinforce the support legs, as they are completely hollow and to screw the table down onto a base, otherwise it's just going to tip over.
The main issue I can see is that, while the two back legs are screwed into a board, there's nothing at all supporting the sliced legs. Cool to look at, but perhaps not the most practical DIY project, unless you stick some thin Perspex cylinders into the gaps so they can at least support a bit of weight.
That said, it should hold a mug and magazine, though probably not a small child looking for something to sit on.
