Stamp command will produce a bitmap image of the sprite, which is stamped onto the stage. This is not a sprite, but an image of a sprite. It can not be programmed. If the sprite has effects, the stamped version will keep these effects ( eg transparency).
Clear will wipe the stamped images from the stage.
Activity 1
Unit 6 is about Art and Procedures ( make-a-block). Today is an exploration of the art tool command Stamp.
Students use the stamp tool to produce beautiful spiral art. Stamp Flower Video
In Nature there is a golden angle that produces amazing spirals. The golden angle is 137.5.
Your students may want to use this angle, (Phyllotaxis), to achieve organic artistic spiraling creations of flowers and seeds.
Activity 2: Stamp as you move the mouse around the stage! This is a short fun activity. Video: StampFollower
