http://www.maplesoft.com/applications/view.aspx?SID=154122&ref=Feed
This application is an educational activity modeling the current system of U. S. Presidential Elections. It is set up in the form of a game in which each player manages a candidate from one of the United States' two major parties. Eight turns simulate an eight week long campaign, with players' decisions affecting the standings of their candidates in state-by-state polls. After the campaign is complete, these polls are used to simulated elections within each state and the District of Columbia and a winner is determined according to the Electoral College results.
This is a modified version of A Presidential Election Game: 2008 Edition and 2012 Edition. Electoral College, candidate and polling information have been updated.<img src="/view.aspx?si=154122/Game_Worksheet_Picture.png" alt="A Presidential Election Game: 2016 Edition" align="left"/>This application is an educational activity modeling the current system of U.

<P>
The <A HREF="/support/help/Maple/view.aspx?path=Fractals/EscapeTime">Fractals</A> package in Maple makes it easier to create and explore popular fractals, including the Mandelbrot, Julia, Newton, and other time-iterative fractals. The Fractals package can quickly apply various escape time iterative maps over rectangular regions in the complex plane, the results of which consist of images that approximate well-known fractal sets. In the following application, you can explore escape time fractals by manipulating parameters pertaining to the generation of Mandelbrot, Julia, Newton and Burning Ship fractals.</P>

http://www.maplesoft.com/applications/view.aspx?SID=135757&ref=Feed
<p>This application takes ranking data from a three person election and creates representation triangles that depict the results of the election both numerically and geometrically for a number of different voting systems. The numerical profile makes it straightforward to calculate the results of the election under a number of different systems while the geometric profile displays the procedure line and the approval voting region and specifically the plurality, anti-plurality and Borda count results. </p>
<p>This is an improvement over the first author's earlier, similar application. The geometric profile is rendered as a two-dimensional object and additional election results are made explicit.</p><img src="/view.aspx?si=135757/135757_thumb.jpg" alt="Representation Triangles for Three Candidate Elections" align="left"/><p>This application takes ranking data from a three person election and creates representation triangles that depict the results of the election both numerically and geometrically for a number of different voting systems.
