Hot on the heels of my post about Director 11 there’s now a web-based version of Hypercard called TileStack. It’s still in beta (aren’t they all?), but you can sign up to test it out or check out the video of it in action.
The original Myst was released as a Hypercard stack and, until the Sims came along, it Myst was the best selling computer game of all time. I’m not just being mysty-eyed (sorry…), for many Hypercard was the forerunner of all that Director and Flash goodness.
