just experimenting with a project by darthpickely .. it uses a sprite to as a sensor.. This project has two sensor sprites..which respond to invisible sprite objects hidden randomly on the screen,, music is from a project by fan music.. press space bar to clear screen and to relocate locations of the invisible sprites.. (it works ok off line in scratch program have not tested this online yet.) --------------------------------------------- original project notes.. "fine. I was testing out this Idea I had for a relative mapping lensing thing, which showed motion relive to your immediate surroundings, and to the neighborhood, the city, the country/region, etc. especially to show motion. you can't see a truck is moving from a map zoomed out to show the whole scale of the travel, because it isn't very noticeable. of course generating this thing in scratch wouldn't be easy anyways. I was just testing the math."
