Spider Projection
This video installation took place in Saarbruecken, Germany. Two small spiders were filmed in a small model of the building that later was projected on.
Computing
PyLab MatPlotLib Matlab like Software
matplotlib is a plotting library for the Python programming language and its NumPy numerical mathematics extension. It provides an object-oriented API for embedding plots into applications using general-purposeGUI toolkits like wxPython, Qt, or GTK+. There is also a procedural "pylab" interface based on a state machine (like OpenGL), designed to closely resemble that of MATLAB. SciPy makes use of matplotlib.

MOSFET Transistor Array CD4007 Parameters – Level 8 Spice Models with LTSpice Files
Level 8 MOSFET models for the PMOS and NMOS FETs in the CD4007 mosfet array chip courtesy of Dr Lynn Fuller of R.I.T.
- LTSpice Schematic file – All the model parameters are included as spice directives on the schematic so this should be portable and run right out of the box on your machine.
- Plot Specification file – goes with the schematic file and plots the I-V characteristic of the PMOS FET and gm/Id which allows the specific current to be calculated
