"Gambiarra refers to an unlikely mend, an unthinkable coupling, a solution so raw and transparent that it illustrates the problem at hand instead of eliminating it."
In Brazil, "gambiarra" is the art of improvising makeshift repairs - spontaneously solving the problem at hand with whatever is in hand. Wikipedia Brazil has a bit more on the topic and how it extends to architecture and programming. Gambilogia is an arts group exploring this DIY aesthetic. Interestingly, there's lots of discussion around gambiarra. Personally, I find the original quick fixes more compelling (examples at bottom of the article).
Some people make DIY drones. Some people build WiFi-hacking UAVs. Somethingawful members build their own submarines, floating launch-platforms, and tow their own manned spacecraft out to sea.
