             Poly 1.09 - J. Tupper | Class2Class


  We are now accepting donations online and by mail from
  members of the web community. Giving to the Math Forum
  allows us to continue offering resources, materials,
  activities, person-to-person interactions, and educational
  services that enrich and support learning. We have put
  donation links on many pages around the site so that it's
  easy to make a contribution if you are interested.

                 FRACTAL LANDSCAPES - Adam Brown


  Adam Brown, who goes by the name "The Ostrich," displays the
  results of his computer programs, which generate fractal
  landscape and landscape rendering. His pages include

    About: illustrated explanation of the fractal
      landscapes project
    Images: gallery of "best" images
    Images 2: gallery of other computer generated images
    Photos: photography gallery
    Maths: introduction to the ideas behind fractal
      landscape generation
    Links: other fractal sites on the Internet


                     POLY 1.09 - Jeff Tupper


  Jeff Tupper has recently announced an update to Poly, a
  shareware program for exploring and constructing polyhedra.
  With Poly, you can manipulate polyhedral solids on the
  computer in a variety of ways. Flattened versions (nets) of
  polyhedra may be printed and then cut out, folded, and taped,
  to produce three-dimensional models.

  For a list of the polyhedra included, please see:

  New features include:
    - Polish and Italian interfaces
    - JIF export
        If the polyhedron is moving or changing, an animated
        JIF is exported; otherwise, a static JIF is exported
    - PCX export
    - Geodesic spheres and domes
        All of the deltahedra currently included have been
        added to a new deltahedra category
    - Available Polyhedron Categories preference controls

  Also available in an updated version is Poly Pro 1.09


                 CLASS2CLASS - The Math Forum


  Class2Class, a service created by Melanie Sprouse and hosted
  by the Math Forum, connects distant math classrooms in
  collaborations such as data-collecting experiments, taking
  advantage of one of the powerful features of the Internet:
  connecting people and information at a distance.

                        COMMON CENTS
              A Pooled Data Analysis Project

  The goal is to collect and share data with other classes.
  Ever think about how many pennies are in circulation? How
  long they last? Classes will organize and count coins by
  date. The data will be shared and each class gets experience
  graphing, looking at variability and central tendencies.
  Common Cents is a project you can do with a set of pennies
  or really any coin.
