Stock Market Lingerie

For this project I was interested in addressing the relationship between sex and the stock market. In my research I discovered several studies that had been conducted on hormonal changes in men who play the stock market. It was found that men who are successful in big trades in the stock market have higher levels of testosterone, in particular right after increasing profit, and further that this level of testosterone makes the men more likely to engage in further risk-taking behaviour (financially and not). It also makes women more attracted to these men. One can surmise that this increased testosterone level may also increase sexual desire, as well as a sense of power and self-worth, and the desire to dominate and conquer.

Circuit - Inside Front, Sides

As the “man” undresses the “woman” (I’m being presumptuously hetero-normative here), the undoing of each clasp of the boustier triggers a web-based update on the latest stock market trades via Yahoo! Finance.

I have chose five multinational corporations that are controversial and in my opinion have significant impact on the general well-being of the global population.  These companies are: Monsanto, DOW Chemicals, BHP Billiton, General Electric, and Bombardier.  They tie into the idea of male dominance, power, control and economics.

Clasps turned into electronic switches

Ideally I would like audio to be triggered but I need something discrete and sewable, and my Arduino audio shield is much too bulky to put on a piece of lingerie, and not physically suited for the Lilypad Arduino (this speaks to a need for an audio shield for the Lilypad Arduino). Working around this temporary problem I resolved that when the clasps on the boustier are opened, the serial monitor in Processing prints the latest stock quotes from Yahoo!

    Erin!!! I LOVE THIS!!
    Please promise me you will finish it?

    Yeppers! I’m loving it too.
    I just had an idea of how to deal with the size of the TTS library, so I may succeed with the audio yet!
