I built my first commercial app for the Mac in 1984. WinMath was one of the first graphing calculator for modern computers.
After that my professional career took lots of interesting twists and turns: I worked at Apple for 10 years bringing the Mac OS X UI to life, then at Adobe building tools for creative professionals.
All the Cortex components are available under an Open Source license.
I can’t wait to see what you do with them. Enjoy!
