Entirely transparent or translucent devices, which are also flexible are becoming less of a dream and coming closer to reality.  We have discussed RRAM quite a bit here on PCPer, most recently another teams research on creating transparent and flexible RRAM out of indium zinc oxide materials.  Nanotechweb have just linked to another set of researchers who are using aluminium oxide to design similar RRAM; great news as more research on the possible materials which will bring us the next generation of RAM the better.  Materials pricing is very important and as we move away from silicon the more choices manufacturers have, the less likely we will have shortages and prohibitive cost increases for production.  Pop over to Nanotechweb for an overview of this particular research if you are so inclined.

"Among the emerging memories, resistive switching memory (ReRAM) in particular has attracted much attention in recent times owing to its fast switching, simple structure, and non-volatility. Flexible and transparent electronic devices have also attracted considerable attention for making future electronic devices."
