Design you own beam-forming microphone array, or come up with a novel application for this integrated one. DSP Codecs Use Beamforming to Optimize Voice Signals | Embedded content from Electronic Design.
No screen, for use with computer but potentially very useful for projects.
MGC3130. The MGC3130 is the world’s first electrical-field (E-field) based three-dimensional (3D) tracking and gesture controller. The chip is based on Microchip’s patented GestIC® technology and enables user command input with natural hand and finger movements in free-space. The GestIC Colibri Suite is processed on-chip and enables a wide range of gesture applications shortening development cycles of developers. Through its configurable sensing states mobile friendly power consumption as low as 150 microwatts can be realized.

Anadigm® makes a field programmable analog array that allows for dynamic synthesis of analog circuits (much as an FPGA does for digital circuits). This might be useful as a general purpose signal conditioner – or perhaps used with a genetic algorithm for analog circuit design.
