Eyal Burstein has designed a series of objects he calls Progress Bar. They measure long terms goals or wishes, creating an emotional link to the passing of time. There’s a model that runs for 18 years with each band represents one year. Other models span over a shorter period of time, like one month. The Progress Bar serves as a gentle reminder, requiring very little attention or upkeep.

I asked Eyal a couple of questions:

How does it work exactly?
1. you make a wish,
2. set the time by turning the top cap
3. Leave to do its thing

What makes it better than websites such as 43 things?
It is very much in that world. Though this object measures promises and wishes which are very hard to quantify. i.e. wishing to move country, be thinner, be a better person. These ideas are ‘Big’ they change your life but also they do not occupy it constantly, the progress bar serves as a gentle reminder.

If i have three wishes, i need 3 measurers?

I think this object is a gift, it is a gift from someone close, someone who understands the significance of a certain event or decision. So you may end up with many but I would imagine you would have only one.
