senso

Senso is a game where you have to repeat a random melody, that gets longer and faster with every round. How long can you follow Senso? You can also play it with multiple players by exchange the mouse with every round. I used to play Senso in the 70's when it was a brand new hardware-electronic-game, that I got as a birthday present. With the new Scratch 1.3 list-variables it took me one afternoon to design and implement it in Scratch. I used it as a test for the new Scratch 1.3 capibilities, that I like a lot. Now at 15.09.2008 it works even in the Online-Player. After putting it online today at 7.8.2008, I found out, that it deosn't work in the Scratch-Java player: There seemed to be a bug. But now everything works fine: The Scratch team found the bug and solved it.

kaleidoscopePlus

kaleidoscopePlus is based on ericr's http://scratch.mit.edu/projects/ericr/626 with many extensions: * Choose number of rays * Choose ColorSchemes * Raythickness depends on distance to center * Forced symetric borders by "Circle-Jump" * Mystic fog-pulsing ... up/down = move forward / backward left/right = trun left / right (holding increases turnspeed) 0-9 = set number of rays A = Colorscheme Uni B = Colorscheme Mix C = Colorscheme PositionDependent D = Colorscheme ChangeByMoving H = Help (English) G = Help (German) There are many parameters on the "Stage" you can play with, if you download it.

Pianist plus Vibraphone

This adds a vibraphone to Jens Pianist project: http://scratch.mit.edu/projects/Jens/12908 Here is Jens description: This project plays random chords and analyzes them on screen. Seven kinds of chords are randomly produced: Major Minor Dominant seventh Minor seventh Dimished Suspended fourth Suspended fourth and seventh Chords are played at random intervals using random bass-keys and a set of five random arpeggios. This produces an 'artsy' Rachmaninoff-like kind of music. Have fun!

Bouncing Balls with Soundcolors

Bouncing Balls with Soundcolors is a much enlarged version of: http://scratch.mit.edu/projects/Canthiar/7369 by Canthiar You now have colors an sounds and many parameters to play with: Up / Down = -/+ Gravity Left / Right = -/+ Emitter Speed B / A = -/+ more Balls 1 = switch Edges 2 = switch Turn Effect 3 = switch Random 4 = switch Drawing 5 = switch Sound Space = start Balls again DragDrop Collision Objects DragDrop Balls DragDrop Emitter Turn Emitter by pulling it's tip H = Help (english) G = Help (german) Chantiers original description: You can move the object emitter around with the mouse and change the direction by clicking on the pointed end. This is what I consider a production version since I've inlined a few things. I have a more academic version that is a little easier to read. The whole thing is also dumbed down a little to make the math a little easier. How it works: When a ball encounters a collision object it uses the [ point towards[ Collision ] ] command block and then uses sin and cos to calculate a colliion normal. That normal is used to calculate a resulting velocity perpendicular to the surface and velocity tangent to the surface. Friction and restitution are applied to make the ball bounce.

Dance of the Suns

Dance of the Suns is a work of Computer Art Only the Start Configuration is set up by Random. Everything else is determinated. There are lots of parameters at the stage, that you can play around with if you download it.

Sounds Of Gravity

Work of Art to play with The Gravity Blocks produce funny sounds while bouncing between the different centers of gravity. Make the edges or circles to centers to Gravity Centers by clicking it. Shift the Gravity blocks from the blue to the white area to activate or deactivate them. If you don't move the gravity centes or blocks, the system will do it for you every 10 seconds. Use Cursor keys to change the size of the objects. Use Space to get new Blocks with differnt sound and colors. Use the 1 2 Key to have a spinning antigravitation beam "Sounds Of Gravity" was inspired by Jay's "Gravity Blocks" at: (link to project) Now (1.June07) it also got the better "sprite moving" method of (link to project)
