Using free web design tools in any classroom situation

I've been directing technology-led art projects for over 30 years as analogue became digital and chemical became digital. As a teacher,  musician and exhibiting artist, the success of my work has been directly related to my ability to maintain a constant connection to contemporary developments in technology and digital design. The tools I use are tools I give to my students not just for art but for life. I want to share some these easily accessible tools with you and hear how you think you can apply them to your own working and teaching environment.
