Nah not really, i am out of ideas for what to do with it! I have 6 small projects but could do with a couple more to include with the set. Its a giveaway, kind of like a business card for county fair coming up. The 90 second charge thing on the site is just that, leave it charging a while and it lasts a long time if you use the low power tricks.
I got the boards free, so apart from a couple i have kept, i decided to hand out the others as a sort of business card. They are designed as a badge which is cool, they can do a fair bit and have some power in them.
