The MTG group at Pompeu Fabra reports that Björk will use the Reactable in her upcoming tour:

With her first tour concert at the Coachella Festival in California, the Icelandic singer Björk introduced the reactable for the first time to a mainstream audience. Our instrument will form a key element of the artist’s current world tour “Volta” which will appear at numerous music festivals during the next 18 months.

I have tried the Reactable at various conferences and it is great that this innovative collaborative instrument gets some attention outside the music tech community.
