Karl Ramberg uploaded a new version of Morphic to project Etoys:
http://source.squeak.org/etoys/Morphic-kfr.87.mcz

==================== Summary ====================

Name: Morphic-kfr.87
Author: kfr
Time: 15 March 2012, 10:52:08 pm
UUID: d52080e7-e1d8-4c55-82a9-65d2bae064bb
Ancestors: Morphic-bf.85

Slight adjustment in parameters that define the x-y plane, to make the way tick-marks on the two axes line up on the underlying grid more uniform.
