Celebrating Scratch

Last Week, my friends were asking me about Scratch and what they could do with it. I told them I would make a project just for their understanding of Scratch. It includes the ask feature, 3D, Background Effects, Stop Motion and music. Please add your valuable comments for my improvement. Thank you, Ahaan CREDITS _________ Music - My Mom Earth Picture - My Organic Day

Ptolemaic Geocentric Model

A remix of my project about the Geocentric planetary system of Ptolemy (a simplification, thanks Paddle2See). Learn more about this in wikipedia http://en.wikipedia.org/wiki/Deferent_and_epicycle Click on the green flag to start.

Mars- Retrograde motion

Watch Mars' apparent motion across the Earth's sky as the Earth passes in their orbits around the Sun. The retrograde otbits are caused by the overtaking Mars as they orbit the Sun. Thanks forest for the music "Act of Love". Learn more about the retrograde motion in http://en.wikipedia.org/wiki/Apparent_retrograde_motion Press Green Flag to start....

Thanks mathjp for the fractal music and nevit for background.

Cassini eggs

In mathematics, a Cassini oval is a set (or locus) of points in the plane such that each point p on the oval bears a special relation to two other, fixed points q1 and q2: the product of the distance from p to q1 and the distance from p to q2 is constant. http://en.wikipedia.org/wiki/Cassini_oval (Jean-Dominique Cassini (1625-1712) French astronome). Thanks Paddle2See for the idea/

Cartesian Eggs

René Descartes, a famous French mathematician and philosopher invented the Cartesian coordinates that bear his name, and also discovered an interesting way to produce more egg-shaped curves. A Cartesian Oval is the figure consisting of all those points for which the sum of the distance to one focus plus twice the distance to a second focus is a constant. Thanks to DarthPickley (again) for the idea (diffraction Interference pattern maker v1).

Tesselation_Kangaroos

The idea to make a tesselation and the image of Kangaroo: http://pagesperso-orange.fr/therese.eveilleau/pages/jeux_mat/textes/kangourou.htm

file decoder V4.

decodes messages from number strings to letters. the message can be sent via email, memory stick/pen and msn. decodes messages from DC's V4 coder. does not work online because of the lists.

File coder V4

The new V4 file coder from DC uses lists to display type instead of variables, allowing for potentially infinite length messages without the need for unhelpful "ask" blocks or difficult text editing. Backwards compatable with V3 as long as the message is not longer than V3's capacity. Use this project to make coded messages that are decoded by DC's V4 decoder at the other end. does not work online because it contains lists.
