David Rubin’s bedform-generating code has been implemented in Matlab (in fact, it has been out there for a while). It is a great learning, teaching, and research tool that can be downloaded as part of an USGS open file report. Strongly recommended to anyone having some interest in sedimentary structures, bedforms, and cool Matlab graphics.
That reminds me of something else: it would be nice to have a Matlab version running on Intel Macs. I hope Mathworks will keep its promises and have something ready by early 2007. Having to reboot the iMac in Windows XP is an acceptable solution, but I could live without it [although even Windows XP looks OK on this kind of hardware 🙂 ].
