I would love to get Math Drag'n (aka Symbolic Equation Manipulator) working b/c I don't know of any other free program that allows manipulating equations via drag-and-drop (very useful!). This program works better when you have lots of screen space as it typically has two or three panes open at once, but I hoped it would at still be usable.

Using my N810, I clicked on the install icons for both the bottom two options and the install failed. It said it was unable to find the package file. I looked at the repository it had added to the Application Catalog and it had a blank distribution field. This page has the proper Application Catalog settings for older versions of Maemo (no mention of Maemo 5). When I corrected that I was able to see three Jalimo examples, but not Jalimo itself. Apparently that requires Red-Pill mode. Not exactly something that's going to get widespread acceptance.
