ACSLogo New Version 1.4f

ACSLogo is a Logo Interpreter for Mac OS X.

Logo is a popular language used to teach simple programming by guiding the progress of a ‘turtle’ which moves around a graphics screen.

Despite Logo’s simplicity, complex pictures can be constructed, as the screenshot shows.
A new version is available — 1.4f (January 2009) - which contains some enhancements which have been requested and some bug fixes. You can find out more about the program and download it for free from here.
See more examples in bitmap or svg format.

The <canvas> tag is a new standard for embedding vector graphics in html (it will be part of the HTML5 standard). Latest versions of Safari, Opera, and Firefox support it to various degrees. If your browser supports it, you will see an image on the left. I’ve been trying it out.
DB2 is IBM's mainframe Database server. The DB2 page has some query and programming examples. There are also some links to books and sites on the links page.

Punk Pics - Some pictures I took of various groups in the late 70s.

ACSFilters are filters for Adobe Photoshop. I developed these to work with Photoshop 2.5.1 so they're showing their age a bit now. They still seem to work with later versions of Photoshop in Classic, though. I hope to develop these for OS X soon. Download or see more examples.
