If you want to try out the HyperCard application for yourself (for example, to see its editing tools) you can do so in the browser here:

For Mac users, you can also easily run it on your local machine: https://jamesfriend.com.au/running-hypercard-stack-2014

Also, if you're taken by the HyperCard aesthetic, you be interested in this interactive artwork created in HyperCard (which I contributed technical assistance to): https://www.upprojects.com/projects/commissions/formality/
