I am most interested in verbal math tools as part of my sonification research. What do all of you know about such tools? Are any of you working with Gardner's triangle or his graphics calculator? Are there any other open source programs to help with math formula menipulation and or sonification? If you must quote me, please put your comments first. I have already listened to mine. I read email with speech. So it is not possible to scroll past the quotes without listening to them again, to quickly get to the new information. Thanks much again as always. _______________________________________________ Blinux-list@redhat.com https://listman.redhat.com/mailman/listinfo/blinux-list
