Open Source Agreement
We are excited to be distributing all of Piccolo as Open Source, and
even more excited about building up a community of developers and
users who believe in the potential of the new kinds of interfaces
that Piccolo
enables. We want to see Piccolo become a broad platform for
innovative user interfaces, not just for experimentation but
real-world applications, including proprietary and legacy
applications. And we want you to download the code, use it,
build applications with
it, find bugs in it, change
it, send it to all your friends - and then especially, to contribute your changes
back to the rest of the community.

A License Note
We have recently switched from the
Mozilla Public License
to the
BSD license. In practice, this will not have much of an
affect on you, the developer. If anything, it will make your
job easier since the BSD license is quite simple and elegant.

Regarding Patents Commercial applications
using Piccolo need to obtain rights to any relevant patents.
As stated in the 'Readme.txt' file included with the Piccolo
distribution: "The University
of Maryland is not responsible for applications which use
Piccolo that infringe on third party's intellectual property
protection such as patents." While we do not track patents,
there are some patents in place which protect certain kinds
of user interfaces that applications could create using
Piccolo. Thus, commercial software developers may want to
investigate:
- "Fractal Computer User Centerface with Zooming
Capability"
Perlin and Schwartz, New York University, 1994, US.
Patent #5,341,466
- Xerox PARC patents on magic lenses.
