A creation from Bristol University which allows bubbles to be produced which can have images projected onto them and the bubble bursts to produced a scent. Useful for bakers and the like so you can smell to see if a sandwich is good for eating or whatnot. Here is an image:
Now, you probably don't want bubbles that pop so easily that you only see the image for a split second because that would be LAME!
Or imagine that you are you in your office and the bubble floats past and tells you how many unread emails you have. CLEVER EH!
