This spectacular urban art project sits at the intersection of guerrilla installation art, recycling, upcycling and freeganism, from interactively mapping empty dumpster locations and full dumpster contents to providing tools for converting materials within them and the skips themselves into new objects and useful spaces.

One of the easiest and yet most impressive of these so-called skip conversions is quite simple yet equally compelling: a swimming pool created simply by lining the interior of a dumpster, adding a latter and filling the result with water.

A few pieces of bent plywood and some tape and one of these dumpsters can also be turned into a miniature skate ramp complete with curved slopes and side rails.

A somewhat more cozy conversion, there is plenty of space for some simple wallpaper, a rug, some seating and even a television set within a single dumpster with walls on all sides.

Need a place to go on the go? There are rarely enough public restrooms in urban areas, but with some on-site facilities and built-in privacy a covered dumpster will do in a pinch.

For those who do not have the space to grow a lawn in the city, a bed of soil and some sod can turn an old rusty dumpster into a green picnic or public lounge space.

Similarly, it is not too difficult to transplant some flowers, fruits and/or vegetables into one of these units and create a small urban guerrilla garden - possibly even with useful food-producing plants.
