Kurt Schwitters: Art mash-ups

In 1923 Kurt Schwitters began to construct his ultimate work of art.

It began as disparate pieces of collage and assemblages round the studio walls, which over time were connected by string, then wire, then wood, and finally plastered wood.

His "Merzbau" gradually took over the downstairs and when it required more space for expansion, Schwitters cut a hole in the ceiling and gave notice to his upstairs lodgers. Into the individual "grottos" of the Merzbau Schwitters placed a bizarre collection of objects gathered from his friends and fellow artists, anything from a stolen sock to a broken pencil.

A composite application defines an application built by combining multiple existing functions into a new application

Composite applications often incorporate logic to control how the multiple functions interact with each other

People often compare composite applications to mash-ups.

According to Wikipedia,Composite applicationsLeverage enterprise-ready sources ofinformation, while mash-ups rely on web-based, and oftenfree sources.

This ischanging.
