Custom Sculpt This is part of the frame for the Integral Farm Greenhouse, and saves 7 prims per frame segment. As we use several hundred frame segments, this is a very significant saving.
In addition most of the UV sculptures in use for terrain and the mega-cave on SmarterSpace were produced by Brice Bonnetto of SDS, and a number of exhibits by him are featured in the permanent collection on display in the Annex.
Grotto Components Jemma kindly provided us with a huge selection of underwater organisms for the grotto, greatly contributing to the overall appearance of the Grotto.
Vegetation I have been known to use vegetation from other suppliers from time-to-time, but only when Heart's does not have an equivalent. This is because there are no other suppliers in SL who understand botany better or translate that into SL plants conveying even a fraction of the realism deeply embedded into every one of the Heart's products. And their new low-prim plants are a builder's delight.
I'd have written a paen like this on the supplier page even if they had not sponsored SmarterEarth with their products. Their generosity just makes it even more of a pleasure.
