[Pipet Devel] icons

[J.W. Bizzaro]

The saga continues.  Below are 17 icons we should probably have made for
Pied/Piper.  We need to give some idea as to what each icon should look like. 
Feel free to provide a descriptions where needed.

Jean-Marc, about categorization, do you think we could put some of the more
special-purpose nodes (like VQ and NNet) in a "Misc" category?

(I'm going with a "water" theme here)

1.    Network/Subnet

          Tangled pipes

2.    Processor

          A waterwheel

3.    Format Converter

          2 pipes, different colors, connected in the middle,
          but bending to point in opposite directions (left & right),
          forming an "S" shape

4.    Viewer

          An aquarium?  :-)

5.    Empty Document

          An empty sink

6.    Filled Document

          A sink full of water

7.    Database & Filesystem

          barrel or metal drum

8.    Iterator

          3 pipes in circle, something like the "recycle" logo

9.    Logic

          A water valve (like on a faucet)

10.   Flow

          A drop of water

11.   General/Misc/Unknown

          A monkey wrench

12.   IO

          An open-ended pipe

13.   Probe

          ?

14.   Math

          Arithmatic symbols

15.   VQ (vector quantization)

          ?

16.   NNet (neural networks)

          ?

17.   Signal

          Water waves


There are also signal types, but do we really need separate icons for them
right now?

18.    Base
19.    DSP
20.    Audio
21.    Manip
22.    Misc
23.    IO


Cheers.
Jeff
