I picked this item because I though the idea of creating cubes was interetsing and fun, and because it reminded me of the old Coub format (sometimes incorrectly called 'cubes') for short video loops (it's what we had before we had TikTok). But when I followed up on the link to Cube Creator to try it out I discoved it was based on an old Flash application. So here's a message to all those ed tech websites highlighting nifty toolss and such: Flash is dead. It is dead for some very good reasons. Review the things you are recommending and make sure they don't use Flash.
