The hand symbol made popular by Rajinikanth has a startup in Mumbai worried. The hand position that the actor-and-would-be politician is known for is often likened to "Apana mudra", a yoga finger and palm posture. And now, Mumbai's Voxweb, an 18-month-old social networking app, says that it is similar to its logo. The actor holds the two middle fingers down with his thumb and raises the little and index fingers in a broad vee. The startup has written to the actor over the issue but is yet to hear from him. Asked what measures he planned to take to save his logo from the Rajini juggernaut, Mishra said his moves would depend on the new political outfit's reactions. Rajinikanth had said last month that he would soon launch a political party in Tamil Nadu.
