The best three ideas .....

My favourite ideas all relate to interactive codes that include both colour and movement.....
The first idea is the colour wheel......

This will be done by using clear plastic card which is 10c persheet.... I would need like 10 to 20 (just in case for mistakes also), these sheets would need to be coloured with different paints which I already have and a split pin which would only be a few dollars. the split pin would be pushed through all to create the wheel effect and allow the wheel to spin which would help to mix the colours. I think this is the most simple idea and shows how when there is one slide...... code........ it is one way but when another slide is added......... an if statement...... it appears another and when the another slide is added........ an else statement........... another variation can be seen. It would also be the most cost affective however I don't know how well the colours will mix...

My next idea is using coloured lights to create images in the dark....   

This idea will involve glow in the dark pens and a dark box with paper...... I would make pens using glow in the dark paint and those glu / glitter pens this would cost roughly ten dollars....  I would also need to make a dark box with a viewing hole and place to put hands this would require cardboard... black material..... glue and dark sunglasses so roughly twenty to thirty dollars and paper which I have plenty of..... this metaphor shows the if/else statement because it allows interaction ..... which shows the change from one position to the adding of the new position.... with the glow in the dark pen if i could I might like to further this idea and have a light table that shines a colour and cover it with dirt or sand and allow for it to be drawn on thus creating the same effect but in a more unusual/ innovative way....

The last idea is my favourite the one using a gobo ......

This idea show perfectly how many if / else statements can change a code in a way that is familiar to anyone who has been in theatre, to a club or a disco...... I will create it sin a lamp which I already have , cardboard and cellophane.... this gobo lighting will be on a way smaller scale and will point only down. the light will be centred over a box type thing that will be used to slide gobo wheels in and out.... I will make numerous different gobo some with patterns simply by using cardboard to make a stencil and some with just cardboard has the border and cellophane to make colour appear... I think this is the best idea and shows both how if/else statements can change the code and therefore the appearance and also how the if/else statements can be complicated
