Here's a great idea - Clocks from recycled vending machine coffee cups and they look fantastic as well! 

The clock and thermometer combination range are designed to be weather proof, so be can be used inside or out. The clean, contrasting Tradiotional design can be easily read from the far end of the garden! 160x260mm in dimention. Wall mounted. Comes with full instructions and guarantee.

The entire range of clocks from the ashortwalk recycled range are hand crafted in the UK and made from vending machine coffee cups direct from the national Save-A-Cup scheme. http://www.save-a-cup.co.uk/

At work buy one vended cup of coffee today, drink the coffee, place the plastic cup in the recycling bin, and see if it's home time on your wall clock made from plastic cups next week. The recycling loop has been closed!

Do a little - change a lot
