I am currently building three new and improved sponges. The most notable difference between these sponges (version 2012) and the old one (2011) is the amount and position of the buttons. There are now ten buttons: five for each hand.
Other changes include:
- The sensibility of the accelerometers can be switched between 1.5g and 6g (it used to be hardwired to 1.5g).
- It is thinner (it used to be 7cm thick, it is now 3.5cm).
- It is sturdier.
- It is shinier.
