This week’s Thursday we faced the first big choices during our project. We had to decide that which ideas we came up during last month, were good and usable enough to implement in an actual concept coin. When we started to go through our ideas I think we were first a little too critical against our thoughts. Almost none of the ideas seemed useful. However, after we discussed and considered our most promising ideas for a while, we came up six great features that we are going to try to attach in our concept coin:

1. OLED / LED – light. Lights would give shining and standout appearance to the coin and make it easier to differentiate the coins from others. Lights might also go around the coin's outer circle so that the coin could also be used to follow time.
2. Validation of the coin based on the wave length of lights.
3. Glowing materials. Those materials are UV-active so the coin would shine in the dark after exposed to daylight. The coin might also be used to follow the amounts of UV-radiation, so you would know when it's time to leave the beach without burning your skin.
4. Self-cleaning surface. Based on our survey coins are considered to be dirty. This coating would ensure the cleanliness of the coin and make it even antibacterial.
5. Material selections. Middle part of the coin needs to be transparent that there is some use of the lights. Outer layer will be some metal alloy.
6. Form of the coin. Our design specialist Ari got a great idea about the outlook of the coin. It would be circle or slightly oval with eccentric transparent centre. This would provide fresh look to the coin and also ensure more use to the coin than just for trading.

Now we have finally gone through our planning face and are starting to make our ideas concrete in the form of the concept coin. In the end of the day I can say that if we’ll be able to attach the features above to our coin, the outcome will definitely be great!
