I second the Road Warrior as an alternative to a Monster product. It's very light, with the wrap around cord making most sockets reasonably near a desk or nightstand usable. Another consideration might be this Asium three grounded outlet model, although it costs double now than when I bought it:

In addition to the Kikkerland "toy" mentioned above, there's also the Neo brand in three cool colors:
