I decoded this transaction but the scriptsig was weird. Can someone explain what is happening with it and how to create one like it.

Raw transaction:
0100000001a30562a1cd9e907a90d7367ceaf55e859417a53ffda6190086110b7f8a4b4d2201000 000020151ffffffff0130d397000000000017a91469d98314fbc4dbee037f86f51392a14c4c1d41 da8700000000
