Yep, you can ice climb inside now. And I don't mean dry tooling on chain links or hanging on urethane holds waiting for the plastic to crack. A relatively new company, Iceholdz, has been perfecting the process of usable indoor ice features for a couple years and they are really turning out a usable, and unique, product. Think of a healable cutting mat, but harder, and 3 dimensional. The maleable plastic of the icehold can be used hundreds of times before your pick won't stick anymore. Iceholdz even recycle old holds and offer you discounts on the replacements. A lot of people ask these questions: How do they feel? or Do they even work?
