Drivable grass ~ create a "green" driveway using porous concrete grids that are planted with a ground cover between the cement ‘pavers’. A creative & environmentally friendly storm water management solution. You can mow your driveway :)
Succulent tree trunk - instructions are not in English but the idea is pretty basic. Tree trunk + removal of some wood + soil, water & succulents = awesomeness in your garden! You could even hang this from a patio at eye height.
