I would be interested to see the condition of these grass pavers after a year of growth and subsequent winter. Grass pavers are often used in more moderate climates for areas of limited use (overflow parking, emergency access, etc..) Often when subject to heavy traffic and winter snow removal forces (especially de-icing material application) the grass fails to grow and the material falls victim to differential settling (creating tripping hazards). Additionally with heavy foot traffic the "plugs of green" often succumb to compaction and fail, leaving a bunch of mud.

Novel idea and definitely more aesthetically pleasing than some hardscapes. I would be interested if BRO revisited this site the condition of the grass paviers in a year and a half. The proof is in the pudding.
